Saint Gertrude Bastion in Gdańsk

Saint Gertrude Bastion is a five-sided fortification in Gdańsk with three distinct levels: a low rampart at the base, a higher central wall, and a gun platform on top. The structure demonstrates the geometric precision of early modern military design and was built as part of the city's integrated defense network.

Construction took place between 1593 and 1607 under architect Anthonis van Obbergen's direction. It was built in response to advancing military technology to protect the city from contemporary threats.

The name comes from the adjacent Saint Gertrude Hospital that once stood nearby. This fortification reflects how military design evolved from medieval to early modern times in Northern Europe.

The interior is closed to the public, but you can view the exterior from nearby walking paths. The area has recreational trails and bicycle lanes that make it easy to circle the structure and see it from different angles.

Beneath its three levels were multiple casemates that served as ammunition storage and powder magazines. These underground chambers were essential to the fortification's combat effectiveness during active military use.
