The Saint Petersburg Mosque (Russian: Санкт-Петербу́ргская мече́ть), when opened in 1913, was the largest mosque in Europe, its minarets attaining 49 meters in height and the impressive dome rising 39 meters high. The mosque is situated in downtown St Petersburg, so its azure dome is perfectly visible from the Trinity Bridge across the Neva. It can accommodate up to five thousand worshippers.
The founding stone was laid in 1910 to commemorate the 25th anniversary of the reign of Abdul Ahat Khan in Bukhara. By that time, the Muslim community of the Russian capital exceeded 8,000 people. The projected structure was capable of accommodating most of them. The architect Nikolai Vasilyev patterned the mosque after Gur-e Amir, the tomb of Tamerlane in Samarkand. Its construction was completed by 1921.
Worshippers are separated by gender during a worship service; females worship on the first floor, while the males worship on the ground floor. The Mosque was closed to worshippers from 1940 to 1956.
