Tholen's reformed church is a big building in Brabant Gothic style, except for the tower which is built in a style exclusive to Zeeland, most notably to the islands of Noord- and Zuid-Beveland.
The church was founded in the 13th century, and a chapter was attached to it in 1404. The church was then still named Onze Lieve Vrouwekerk (Church of Our Lady). A great fire destroyed most of the town in 1452, including the church. In 1460 the rebuilt was started, which was ended in the early 16th century. The choir was never finished, and is now seperated from the rest of the church by a wall. It's currently being restored. The nave has stone vaults, which explains the presence of flying buttresses on the outside, something which isn't very common in this part of the country.
In 1577 the church was confiscated by the protestants and has remained in their possesion ever since.
