Passantenhaven Maagjesbolwerk is a visitor marina in the heart of Zwolle, situated on the Singelgracht at the foot of the Maagjesbolwerk building.

That striking modern structure, designed by architect Hans Ruijssenaars and completed in 2003, was inspired by the 17th-century bastion that once stood on the same site — its lowest ten meters matching the original bastion's height.

The complex acts as a boundary between the bustle of the city and the calm of the water. The marina's location is notably convenient: shops, markets, cafés, and museums are all within a short walk of the moorings.

Zwolle itself is a hub for inland waterways, offering quick connections to the IJssel and Vecht rivers and onward to the IJsselmeer. Note that the right-hand section of the harbor is accessible only to vessels with a beam of up to 3.

95 meters due to a footbridge. The marina operates from 1 April through 31 October.
