The height is 61.5 meters (including the spire) and consists of three sections with right-angled buttresses, decorated with philo bundles. Brick, richly decorated with Lede and Bentheimer stone and patterns of glazed bricks. Each facade has two traced niches in each facade. On the northeast corner a staircase tower. Short, octagonal section as a start for the spire.
Only the beginnings of the vault over the lower space have been executed. Bell frame with three bells, cast by Aelt van Meurs (1581), diameter 135 cm, Steven Butendijc (1581) and Jan van Vorscoten (1625), diameter 119,5 cm. It also contains a clock. The carillon was cast in 1965 by Bell Foundry Petit & Fritsen. The copper sundial is from 1785.
The tower belonged to the Gothic cruciform church with a central nave and two side aisles of equal height, which was demolished in 1844 (see Groenmarkt 7).
