Churches in Brest, Belarus, Former Orthodox church site in Brest, Belarus

Saint Nicholas Church in Brest was a stone church, left unplastered, with a shingle roof and a wooden dome at the centre, its top sheathed in white tin and topped by an iron cross. A wooden porch stood at its side. Its plan formed a cross close to the Balkan triconch type, and the front façade carried two towers.

First mentioned in 1390 as a cathedral when Brest received Magdeburg rights. In 1596 the Union of Brest was signed in the church, which then became Greek Catholic. After the 1839 dissolution of the union it passed to the Russian Orthodox Church, and in 1840 the ancient church was dismantled during construction of the Brest Fortress.

The church was the site of the 1596 signing of the Union of Brest, which created the Ruthenian Uniate Church. In 1593 Bishop Ipatiy Potiy granted a charter and endowment to the royal burghers of Brest to found a brotherhood at the church, with its own court, vestments and alms. The charter mentions a large altar dedicated to Saints Boris and Gleb.

The church no longer exists: it was dismantled in 1840 during the construction of the Brest Fortress. Visitors to the fortress site can look for the two 1840 paintings by Martin Zaleski showing the demolition, and for the 1837 measured drawings made when a garrison conversion was still planned.

The church was demolished in 1840, not preserved as a standing building. Its plan was cross-shaped, close to the Balkan "triconch" type, and it had two towers on the front facade. The painter Marcin Zaleski depicted its demolition in two 1840 canvases of the fortress under construction.
