Church of All Saints at Kulishki is one of the oldest churches in Moscow, located at 2 Slavyanskaya Square. A notable feature of the church is its leaning bell-tower.
The first wooden church at this place was built by Dmitry Donskoy most likely in 1380 after the Battle of Kulikovo. In the 14th century, the place chosen for the church was far away from the border of Moscow and the word kulichki became a synonym for at the world's end or in the middle of nowhere, but now it is at the historical center of Moscow.
The church was completely rebuilt in stone in 1488 and again in the Muscovite Baroque style in 1687-89.
