The Church of the Assumption of Virgin Mary is the most valuable sight of the Gothic Cistercians' architecture in Bohemia. The construction lasted for more than 100 years (1280 - 1385). Three aisles were built between 1360 - 1385 and they adjoin with a transept (from the beginning of the 14th century) and with a presbytery from the end of the 13th century. The pair of chapels (consecrated in 1316) butts on the presbytery from both sides.
The first reconstruction of the church was at the beginning of the 19th century - the Neo-Gothic tower with the pyramidal roof was added.

The interiors of the church are arched with ribbed and cross vaults. The most interesting relic is the painting of Madonna of Vyšší Brod from about 1420. Only the copy is in the church; the original is deposited in the National Gallery in Prague nowadays, together with the altar paintings from Master of Vyšší Brod, which are counted among the most valuable works of the Czech Gothic art of painting.
The Early-Baroque main altar comes from 1646.
