Galluswarte, Medieval stone watchtower on Mainzer Landstraße in Gallus, Frankfurt, Germany

The Galluswarte is a stone watchtower built around 1400 that was part of Frankfurt's medieval defensive fortifications. The structure stands in the Gallus district and remains recognizable among the surrounding modern buildings today.

A wooden watchtower called Warte zu den guten Leuten stood here first, named for the pious brotherhood that ran a leper station at the Gutleuthof. In 1414 it was replaced by the surviving stone tower, then called Galgenwarte after the Galgenfeld to the east, where Frankfurt's gallows stood near today's Taunusstraße. In 1903 the new St.-Gallus parish gave the tower its present name.

The tower's name changed over time: it was first called Warte zu den guten Leuten, after the pious brotherhood running a leper station at the Gutleuthof, then Galgenwarte after the Galgenfeld to the east, where Frankfurt's gallows stood near today's Taunusstraße. In 1903, when the St.-Gallus parish was founded, it was renamed Galluswarte.

The tower is located near Galluswarte station and is easily accessible by several S-Bahn train lines. The surrounding streets are walkable, and you can view the structure from outside, though it cannot be entered.

The tower is one of the few surviving remnants of Frankfurt's medieval fortifications, as many structures from this period were lost during the war. Its survival makes it a rare witness to the original city defense system in this form.
