Located just off Nevsky Prospekt down Ulitsa Poltavskaya is one of St Petersburg's lesser known cathedrals - the Our Lady of St Theodore Cathedral, which was built between 1911 and 1914 for the 300th anniversary of the House of Romanov. St Theodore was considered the house's patron saint and his icon was especially revered by the imperial family. Although the cathedral dates from the early 20th century it was built in the Rostov style common during the reign of the first Romanov tsar, featuring a tall cubic structure with five domes.  After the Revolution worship at the cathedral was limited and it was completely closed in 1932.  The building was later used as a dairy plant which existed up until 2005 when the building was returned to the Orthodox Church.  After major restoration work the cathedral was reopened in 2013.
