A lintel or lintol is a type of beam (a horizontal structural element) that spans openings such as portals, doors, windows and fireplaces. It can be a decorative architectural element, or a combined ornamented/structural item. In the case of windows, the bottom span is referred to as a sill, but, unlike a lintel, does not serve to bear a load to ensure the integrity of the wall. Modern-day lintels may be made using prestressed concrete and are also referred to as beams in beam-and-block slabs or as ribs in rib-and-block slabs. These prestressed concrete lintels and blocks can serve as components that are packed together and propped to form a suspended-floor concrete slab.
In worldwide architecture of different eras and many cultures, a lintel has been an element of post and lintel construction. Many different building materials have been used for lintels.[3]
In classical Western architecture and construction methods, by Merriam-Webster definition, a lintel is a load-bearing member and is placed over an entranceway.[3] The lintel may be called an architrave, but that term has alternative meanings that include more structure besides the lintel. The lintel is a structural element that is usually rested on stone pillars or stacked stone columns, over a portal or entranceway.
A lintel may support the chimney above a fireplace, or span the distance of a path or road, forming a stone lintel bridge.
The use of the lintel form as a decorative building element over portals, with no structural function, has been employed in the architectural traditions and styles of most cultures over the centuries.
Examples of the ornamental use of lintels are in the hypostyle halls and slab stelas in ancient Egypt and the Indian rock-cut architecture of Buddhist temples in caves. Preceding prehistoric and subsequent Indian Buddhist temples were wooden buildings with structural load-bearing wood lintels across openings. The rock-cut excavated cave temples were more durable, and the non-load-bearing carved stone lintels allowed creative ornamental uses of classical Buddhist elements. Highly skilled artisans were able to simulate the look of wood, imitating the nuances of a wooden structure and the wood grain in excavating cave temples from monolithic rock.[4] In freestanding Indian building examples, the Hoysala architecture tradition between the 11th and 14th centuries produced many elaborately carved non-structural stone lintels in the Southern Deccan Plateau region of southern India. The Hoysala Empire era was an important period in the development of art and architecture in the South Indian Kannadiga culture. It is remembered today primarily for its Hindu temples' mandapa, lintels, and other architectural elements, such as at the Chennakesava Temple.
The Maya civilization in the Americas was known for its sophisticated art and monumental architecture. The Mayan city of Yaxchilan, on the Usumacinta River in present-day southern Mexico, specialized in the stone carving of ornamental lintel elements within structural stone lintels.[5] The earliest carved lintels were created in 723 CE. At the Yaxchilan archaeological site there are fifty-eight lintels with decorative pieces spanning the doorways of major structures. Among the finest Mayan carving to be excavated are three temple door lintels that feature narrative scenes of a queen celebrating the king's anointing by a god.[6]
Radiation protection
Lintels may also be used to reduce scattered radiation in medical applications. For example, Medical linacs operating at high energies will produce activated neutrons which will be scattered outside the treatment bunker maze with a dose rate that depends on the maze cross section. Lintels may be visible or recessed in the roof of the facility, and reduce dose rate in publicly accessible areas by reducing the maze cross section.[7]

[...] at last [...] it occurred to some philosopher or mechanic [...] that by arranging small wedge-shaped stones or other materials in a semicircular form, a sort of curved lintel could be obtained, which, though composed of many distinct parts, could be stretched from pier to pier, or from pillar to pillar [...]. [...] There have been, in some stone constructions, what may be regarded as intermediate steps between the lintel and the arch.
A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. The term column applies especially to a large round support with a capital and a base or pedestal, which is made of stone, or appearing to be so. A small wooden or metal support is typically called a post. Supports with a rectangular or other non-round section are usually called piers.
In architecture, post and lintel is a building system where strong horizontal elements are held up by strong vertical elements with large spaces between them. This is usually used to hold up a roof, creating a largely open space beneath, for whatever use the building is designed. The horizontal elements are called by a variety of names including lintel, header, architrave or beam, and the supporting vertical elements may be called columns, pillars, or posts. The use of wider elements at the top of the post, called capitals, to help spread the load, is common to many traditions.
In classical architecture, a pilaster is an architectural element used to give the appearance of a supporting column and to articulate an extent of wall, with only an ornamental function. It consists of a flat surface raised from the main wall surface, usually treated as though it were a column, with a capital at the top, plinth (base) at the bottom, and the various other column elements. In contrast to a pilaster, an engaged column or buttress can support the structure of a wall and roof above.
A torii is a traditional Japanese gate most commonly found at the entrance of or within a Shinto shrine, where it symbolically marks the transition from the mundane to the sacred and a spot where kami are welcomed and thought to travel through.
In architecture, a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket. A corbel is a solid piece of material in the wall, whereas a console is a piece applied to the structure. A piece of timber projecting in the same way was called a "tassel" or a "bragger" in England.
In classical architecture, an architrave is the lintel or beam that rests on the capitals of columns.
A chaitya, chaitya hall, chaitya-griha, refers to a shrine, sanctuary, temple or prayer hall in Indian religions. The term is most common in Buddhism, where it refers to a space with a stupa and a rounded apse at the end opposite the entrance, and a high roof with a rounded profile. Strictly speaking, the chaitya is the stupa itself, and the Indian buildings are chaitya halls, but this distinction is often not observed. Outside India, the term is used by Buddhists for local styles of small stupa-like monuments in Nepal, Cambodia, Indonesia and elsewhere. In Thailand a stupa, not a stupa hall, is called a chedi. In the historical texts of Jainism and Hinduism, including those relating to architecture, chaitya refers to a temple, sanctuary or any sacred monument.
Aihole, also referred to as Aivalli, Ahivolal or Aryapura, is a historic site of ancient and medieval era Buddhist, Hindu and Jain monuments in Karnataka, India that dates from the sixth century through the twelfth century CE. Most of the surviving monuments at the site date from the 7th to 10th centuries. Located around an eponymous small village surrounded by farmlands and sandstone hills, Aihole is a major archaeological site featuring over one hundred and twenty stone and cave temples spread along the Malaprabha river valley, in Bagalakote district.

Lintel 24 is the designation given by modern archaeologists to an ancient Maya limestone sculpture from Yaxchilan, in modern Chiapas, Mexico. The lintel dates to about 723–726 AD, placing it within the Maya Late Classic period. Its mid-relief carving depicts the ruler of Yaxchilan, Itzamnaaj Bahlam III, and his consort Lady K’abal Xoc, performing a ceremony of bloodletting; the imagery is also accompanied by descriptive captions, and a signature by the sculptor, Mo’ Chaak.
The architecture of ancient Sri Lanka displays a rich diversity, varying in form and architectural style from the Anuradhapura Kingdom through the Kingdom of Kandy (1469–1815). Sinhalese architecture also displays many ancient North Indian influences. Buddhism had a significant influence on Sri Lankan architecture after it was introduced to the island in the 3rd century BC, and ancient Sri Lankan architecture was mainly religious, with more than 25 styles of Buddhist monasteries. Significant buildings include the stupas of Jetavanaramaya and Ruwanvelisaya in the Anuradhapura kingdom and further in the Polonnaruwa Kingdom. The palace of Sigiriya is considered a masterpiece of ancient architecture and ingenuity, and the fortress in Yapahuwa and the Temple of the tooth in Kandy are also notable for their architectural qualities. Ancient Sri Lankan architecture is also significant to sustainability, notably Sigiriya which was designed as an environmentally friendly structure.
Indian rock-cut architecture is more various and found in greater abundance in that country than any other form of rock-cut architecture around the world. Rock-cut architecture is the practice of creating a structure by carving it out of solid natural rock. Rock that is not part of the structure is removed until the only rock left makes up the architectural elements of the excavated interior. Indian rock-cut architecture is mostly religious in nature.
In structural engineering, structural elements are used in structural analysis to split a complex structure into simple elements. Within a structure, an element cannot be broken down (decomposed) into parts of different kinds.
Bhaja Caves are a group of 22 rock-cut caves dating back to the 2nd century BC located off the Mumbai - Pune expressway near the city of Pune, India. The caves are 400 feet above the village of Bhaja, on an important ancient trade route running from the Arabian Sea eastward into the Deccan Plateau. The inscriptions and the cave temple are protected as a Monument of National Importance, by the Archaeological Survey of India per Notification No. 2407-A. It belongs to the Early Buddhist schools in Maharashtra. The caves have a number of stupas, one of their significant features. The most prominent excavation is its chaitya, a good example of the early development of this form from wooden architecture, with a vaulted horseshoe ceiling. Its vihara has a pillared verandah in front and is adorned with unique reliefs. These caves are notable for their indications of the awareness of wooden architecture. The carvings prove that tabla – a percussion instrument – was used in India for at least 2300 years, disproving the centuries-held belief that the tabla was introduced to India by outsiders or from Turko-Arab. The carving shows a woman playing tabla and another woman, performing dance.
A bracket is an architectural element: a structural or decorative member. It can be made of wood, stone, plaster, metal, or other media. It projects from a wall, usually to carry weight and sometimes to "...strengthen an angle". A corbel or console are types of brackets.
Da Parbatia is a small village very close to west Tezpur, in the Indian State of Assam. In the village there are significant architectural remnants of an ancient temple of the 6th century overlying the ruins of another Shiva temple built of bricks during the Ahom period. Archaeological excavations done here in 1924 have unearthed a sixth-century antiquity in the form of a stone door frame with extensive carvings. The ruins of the temple built during the Ahom period are built over the ancient temple's foundations and are in the form of a stone paved layout plan of the sanctum sanctorum and a mandapa. This complex is under the jurisdiction of the Archaeological Survey of India and its importance and notability is recorded under the Ancient Monuments and Archaeological Sites and Remains Act 1958.
The Songyue Pagoda, constructed in 523 CE, is located at the Songyue Monastery on Mount Song, in Henan province, China. Built during the Northern Wei Dynasty, this pagoda is one of the few intact sixth-century pagodas in China and is also the earliest known Chinese brick pagoda. Most structures from that period were made of wood and have not survived, although ruins of rammed earth fortifications still exist. In 2010, the Pagoda was inscribed on the UNESCO World Heritage List along with other nearby monuments as part of the 'Historic Monuments of Dengfeng in “The Centre of Heaven and Earth”' site.
The Lakshminarasimha temple at Vignasante is a 13th-century Vishnu temple in the village of Vignasante, Tumkur district, Karnataka, India. The three-shrine temple is dedicated to Venugopala, Narasimha and Lakshmi Narayana. One of the late temples built before Hoysala empire came under sustained attacks from the Delhi Sultanate, it illustrates the mature Hoysalanadu architectural tradition. The fully carved, three storey Vesara vimana of this temple is notable.
The Tomb of Clytemnestra was a Mycenaean tholos type tomb built in c. 1250 BC. A number of architectural features such as the semi-column were largely adopted by later classical monuments of the first millennium BC, both in the Greek and Latin world. The Tomb of Clytemnestra with its imposing façade is together with the Treasury of Atreus the most monumental tomb of that type.
The Buddhist caves in India. Maharashtra state Aurangabad Dist. Ellora caves form an important part of Indian rock-cut architecture, and are among the most prolific examples of rock-cut architecture around the world. There are more than 1,500 known rock cut structures in India, out of which about 1000 were made by Buddhists, 300 by Hindus, and 200 by Jains. Many of these structures contain works of art of global importance, and many later caves from the Mahayana period are adorned with exquisite stone carvings. These ancient and medieval structures represent significant achievements of structural engineering and craftsmanship.
