Bollwerk Tower

The Bollwerk Tower, also known as the Bastion Tower, completes the eastern fortifications of Mulhouse, likely built from the early 13th century.

Constructed in the 14th century near the convergence of defensive moats, it evolved over the centuries. Originally crenellated, it was topped with a four-sided roof in the 18th century, then a small bell tower in 1840.

In 1892, its roof took its current form. A symbol of urban defenses, it remains while the walls were demolished from 1809 to modernize the city and the canals gradually covered from the mid-19th century.

Restored in 1893, two openings were added to the remaining wall, allowing the creation of a fresco depicting the 1385 attack on Mulhouse by Martin Malterer. Below, the older imperial eagle recalls Mulhouse's status as a free imperial city granted in 1308.
