Vallon-Pont-d'Arc is a village in southern France in the Ardèche Department.
The National Speleological Society (NSS) is an organization formed in 1941 to advance the exploration, conservation, study, and understanding of caves in the United States. Originally headquartered in Washington D.C., its current offices are in Huntsville, Alabama. The organization engages in the research and scientific study, restoration, exploration, and protection of caves. It has more than 10,000 members in more than 250 grottos.
The Blue Grotto is a sea cave on the coast of the island of Capri, southern Italy. Sunlight shining through an underwater cavity is reflected back upward through the seawater below the cavern, giving the water a blue glow that illuminates the cavern. The cave extends some 50 metres into the cliff at the surface, and is about 150 metres (490 ft) deep, with a sandy bottom.
A grotto is a natural or artificial cave used by humans in both modern times and antiquity, and historically or prehistorically. Naturally occurring grottoes are often small caves near water that are usually flooded or often flooded at high tide. Sometimes, artificial grottoes are used as garden features. The Grotta Azzurra at Capri and the grotto at Tiberius' Villa Jovis in the Bay of Naples are examples of popular natural seashore grottoes.
The Longmen Grottoes or Longmen Caves are some of the finest examples of Chinese Buddhist art. Housing tens of thousands of statues of Shakyamuni Buddha and his disciples, they are located 12 kilometres (7.5 mi) south of present-day Luoyang in Henan province, China. The images, many once painted, were carved as outside rock reliefs and inside artificial caves excavated from the limestone cliffs of the Xiangshan (香山) and Longmenshan, running east and west. The Yi River flows northward between them and the area used to be called Yique. The alternative name of "Dragon's Gate Grottoes" derives from the resemblance of the two hills that check the flow of the Yi River to the typical "Chinese gate towers" that once marked the entrance to Luoyang from the south. There are as many as 100,000 statues within the 2,345 caves, ranging from 1 inch (25 mm) to 57 feet (17 m) in height. The area also contains nearly 2,500 stelae and inscriptions, hence the name "Forest of Ancient Stelae", as well as over sixty Buddhist pagodas. Situated in a scenic natural environment, the caves were dug from a 1 kilometre (0.62 mi) stretch of cliff running along both banks of the river. 30% date from the Northern Wei and 60% from the Tang dynasty, caves from other periods accounting for less than 10% of the total. Starting with the Northern Wei dynasty in 493 AD, patrons and donors included emperors, Wu Zetian, members of the royal family, other rich families, generals, and religious groups.
The Yungang Grottoes, formerly the Wuzhoushan Grottoes, are ancient Chinese Buddhist temple grottoes built during the Northern Wei dynasty near the city of Datong, then called Pingcheng, in the province of Shanxi. They are excellent examples of rock-cut architecture and one of the three most famous ancient Buddhist sculptural sites of China. The others are Longmen and Mogao.
Phong Nha-Kẻ Bàng is a national park and UNESCO World Heritage Site in the Bố Trạch and Minh Hóa districts of central Quảng Bình Province in the North Central Coast region of Vietnam, about 500 km south of Hanoi. The park borders the Hin Namno National Park in Khammouane Province, Laos to the west and 42 km east of the East sea from its borderline point. Phong Nha-Kẻ Bàng National Park is in a limestone zone of 2,000 km2 in Vietnamese territory and borders another limestone zone of 2,000 km2 of Hin Namno in Laotian territory. The core zone of this national park covers 857.54 km2 and a buffer zone of 1,954 km2.
A show cave—also called tourist cave, public cave, and, in the United States, commercial cave—is a cave which has been made accessible to the public for guided visits.
The Jeita Grotto is a system of two separate, but interconnected, karstic limestone caves spanning an overall length of nearly 9 kilometres (5.6 mi). The caves are situated in the Nahr al-Kalb river valley within the locality of Jeita, 18 kilometres (11 mi) north of the Lebanese capital Beirut. Though inhabited in prehistoric times, the lower cave was not rediscovered until 1836 by Reverend William Thomson; it can only be visited by boat since it channels an underground river that provides fresh drinking water to more than a million Lebanese.
The Pyramid of the Sun is the largest building in Teotihuacan, and one of the largest in Mesoamerica. It is believed to have been constructed about 200 CE. Found along the Avenue of the Dead, in between the Pyramid of the Moon and the Ciudadela, and in the shadow of the mountain Cerro Gordo, the pyramid is part of a large complex in the heart of the city.
Aven Armand is a limestone cave located in the Cévennes National Park of France, in the Lozère département, between Meyrueis and Sainte-Enimie known for the tallest known stalagmite of 30 meters.
São Thomé das Letras is a municipality in the south of Minas Gerais state in southeastern Brazil, 35 kilometres (22 mi) east of Três Corações city. It has a population of 7,120 (2020) with a population density of 18 inhabitants per square kilometer. São Thomé das Letras covers 369.75 square kilometres (142.76 sq mi).
A Grotto is an internal organization of the National Speleological Society (NSS). They generally function as the local NSS chapter/club. Many Grottos however, operate in areas outside their local area, with many operating in several states. Most Grottos also participate in Regions which are loose associations of Grottos. Regions are also an internal organization of the National Speleological Society.
Grotto-heavens are a type of sacred Taoist site. Grotto-heavens are usually caves, grottoes, mountain hollows, or other underground spaces.
Orgnac-l'Aven is a commune in the Ardèche department in southern France.
A cave castle or grotto castle is a residential or refuge castle that has been built into a natural cave. It falls within the category of hill castles. Unlike other types, such castles can only be assaulted from the front, or by drilling through the rock above; the gateway is usually located in the middle of a rock face, which makes it much more difficult to penetrate. Archaeological discoveries have revealed that caves were used as places of refuge as early as the Stone Age. The first medieval cave castles emerged in the 11th and 12th centuries. In the 14th and 15th centuries this type became more widespread, especially in certain parts of France and Switzerland.
The Grotto of Our Lady of Lourdes is located at the University of Notre Dame in Notre Dame, Indiana, United States, and is a reproduction of the Grotto of Our Lady of Lourdes in Lourdes, France. The current Grotto was built in 1896, replacing a wooden grotto built on August 22, 1878. An artificial rock cave, the Grotto is used by its visitors as a sacred space for prayer, meditation, and outdoor Mass.
