Walls of Alcalá de Henares

The Walls of Alcalá de Henares form a medieval stone fortification surrounding the historic center with multiple towers and gates integrated into the perimeter. The defensive structure creates a continuous circuit around the old town with distinct entry points marked by monumental gateways.

This fortification began in the 13th century to defend the town during the medieval period and underwent significant changes under Archbishop Tenorio during the 14th century. These modifications reflected changing military needs and the town's evolving role in the region over time.

The walls shape how people move through and perceive the historic center, with the main gates marking traditional entry points into town. These structures remain woven into the everyday landscape and help residents and visitors understand the old boundaries of the community.

The walls are open to visitors on specific days during limited hours, with free access to tower interiors and an exhibition space inside the Antiquarium. Wear sturdy shoes since you will walk on uneven terrain and climb steps through the historic structures.

The towers retain original defensive features such as arrow slits and roof openings with a machicolation system designed to repel attacks from above. These technical details reveal how medieval military engineering was applied to protect the town.
