One of the most prominent buildings in Ootmarsum is the (former) town hall with its beautifully decorated facade and with the town coat of arms above the entrance. The town hall was built in 1778 on the same site where the Huys der Stadt had also stood since 1564. The new town hall was designed by architect Egbert Schrader.

It became a town hall without a turret. A copper weather vane was put on the ridge of the roof. Only much later - in 1839 - was a turret put on the town hall.

Ootmarsum was a separate municipality until 2001, when it became a part of Dinkelland. Two years later, the town hall was sold by the new municipality. The building then had various functions, but as a national monument it will always remain in Ootmarsum.
