Shukhov Rotunda



Shukhov Rotunda was a round exhibition pavilion built for All-Russia Exhibition 1896 in Nizhny Novgorod, Russia. It was built in 1896 with a diagrid hanging cover (tensile gridshell – diagrid roof, Russian Empire patent No. 1894, dated March 12, 1899) and was the world's first Hyperboloid structure (in the center of the Rotunda). It is named after Vladimir Shukhov, who designed it in 1895.

The Rotunda was 16 m high with a diameter of 68 m. The diameter of the steel membrane was 25 m.

The rotunda was subsequently moved to Yessentuki and demolished in the 1980s.
