Jan Roodenpoortstoren

The Jan Roodenpoortstoren is a stone tower that stood at the intersection of Singel and Torensteeg, serving as a former entrance to Amsterdam's medieval center. The structure reached approximately 55 meters in height and later served dual purposes as both a clock tower and a prison facility.

The tower was built in the late 15th century as a defensive structure protecting medieval Amsterdam. After the city expanded in 1616, the structure lost its military purpose and was repurposed as a clock tower and prison facility.

The tower appeared in 18th century artworks, including reverse glass paintings by Jonas Zeuner, showing how central it was to Amsterdam's visual identity. Artists documented the structure as a symbol of the city's medieval character.

The tower's original location is marked in the cobblestone paving of the Torensluis bridge, allowing visitors to trace where it once stood in the city. The site sits at a central point easily reached on foot from surrounding streets.

Three reconstruction attempts were made during the 20th century using available historical blueprints, but all failed to be completed. Despite adequate funding and detailed plans, the project never came to fruition in its final form.
