The Hanoi Museum and Hong Kong Coliseum are buildings which have an inverted pyramidal shape. The Pyramide Inversée in Paris is a skylight of this shape. The Tokyo Big Sight's conference tower consists of four inverted pyramids mounted on support bases. Whitney Museum is another example and its inverted pyramid design allowed the building to gain an unusual spatial distribution and conform to the New York City's zoning requirements.[1] The Tempe Municipal Building's inverted pyramidal shape helps in keeping the building cool in summer and warm in winter.[2] The same applies to Slovak Radio Building in Bratislava, Slovakia. The inverted pyramid can also be integrated as a component of a structure such as the case of the stalactite work design, which is formed by an intricate corbeling of brackets, squinches and inverted pyramids.[3] In addition to the hidden safety hazards, it is also one of the challenges for the public to accept such a style. At the design level, architects need to carefully consider the design of the internal structure and materials of the building while ensuring aesthetics.
Examples
Boston City Hall

It was designed by the architecture firms Campbell, Aldrich & Nulty and Kallmann McKinnell & Knowles.

Louvre Inverted Pyramid
Louvre Inverted Pyramid
The Louvre Inverted Pyramid (Pyramide Inversée) is a skylight constructed in the underground shopping mall. The glass pyramid designed and built by I.M. Pei is 21 meters (69ft) high and 30 meters (98ft) wide at the bottom, standing in the center of the courtyard.[6] Its four sides are made up of six hundred and seventy-three pieces of diamond-shaped glass. The total floor area is about 2,000 square meters (22,000sqft). The total weight of the tower is 200 tons, of which the net weight of glass is 105 tons, and the metal support is only 95 tons. In other words, the load on the stand exceeds its own weight. It was advanced to the final of Benedictus Awards in 1995.

Limitations
Inverted pyramids, with their narrow bases, are inherently less stable than more traditional structures. This poses engineering challenges, notably for high-precision manufacturing of materials. [8] Outer structural elements are usually made lighter than the strong core, particularly for structures subjected to earthquakes or high winds.
Criticism
Inverted pyramids are often criticized for their unusual aesthetics; the Slovak Radio Building, in particular, has appeared on lists of the world's ugliest buildings. [9][10] Architects designing such structures have been accused of deliberately breaking established design principles for shock value and publicity. Structures like Boston City Hall, acclaimed by architects for its unconventional style, remain unpopular with the public for their perceived "inhumanity".
Tourism
Iconic buildings have an enduring presence character, promoting the development of the tourism industry. At the same time, the tourism economy of regions with unique buildings will also be improved accordingly.[11]
Although most architects do not prioritize the tourism effect of a building when designing, it is undeniable that the unique appearance of a building can bring additional tourism value. As a unique architectural style, the inverted pyramid building can also produce certain benefits for the tourism industry. [12]
The Hong Kong Coliseum, as a building opened for use in 1984, has held many large-scale projects such as concerts, music festivals, and university gatherings without interruption. [13] The financial returns of the Hong Kong Coliseum have been at a high level, attracting tourists from all over the world. Among them, between 1992 and 1993, the utilization rate was as high as 91%, and there were more than 2 million paying customers. [14]
Tokyo Big Sight hosts about 300 events every year and is visited by about 14 million tourists from all over the world. It hosts about 300 events every year and is visited by about 14 million tourists from all over the world. In order to cope with such a huge passenger flow, Tokyo Big Sight is about 30 minutes away from Tokyo Station, and about 15 minutes away from Haneda Airport. At the same time, about 4,700 accommodations have been opened around Tokyo Big Sight. [15]
