Architects and designers have always been been inspired by pyramids and several pyramid shaped buildings exists all over the World. However, the architects in Bratislava, Slovak Republic went one step further and designed an interesting inverted pyramidical shaped building for the Slovak Radio.
The building known as 'Slovenský Rozhlas' (Slovak Radio Building) was designed by Stephen Svetko, Stephen Ďurkovič and Barnabas Kissling. The project work was started in 1967 and construction was completed only in 1983.
The building houses contains concert hall and recording studios for the Slovak Radio and has fifteen floors with a total height of 61 metres upto the roof and maximum width of about 74 x 74 metres square.

Although there are several other buildings whose upper floors are larger than the lower ones, but I am not aware of any other building, except the above two, which is a true inverted pyramid. May be my readers can help me in finding some more of these inverted buildings.
The famous inverted pyramid of Louvre is not a building in true sense. It is only a skylight for an underground shopping mall in front of the Louvre Museum. (Source: Wikipedia

The Canadian pavilion at the Montreal 1967 International and Universal Exposition - Expo 67 was also a big inverted pyramid. However it was only a temporary structure and has since been dismantled.

Serendipity brought me today to another inverted pyramid shaped building.
The City Hall of Tempe, Arizona, USA designed by local architects Michael and Kemper Goodwin is another example of inverted pyramid. The building is 3 storey high and its roof measures 126 feet (~ 38.4 metres) on each side.
Completed in 1971, its inverted pyramid shape was designed to conserve energy by allowing less light into the building. In 1971, it received an award of excellence from the American Institute of Steel Construction, and in 1972 received an award of merit from the Western Mountain Region of the American Institute of Architects.
