Prison Arch · Lerma (EN)
POI
Well-preserved residue of the main gate of the Lerma wall. It consists of a turreted arch flanked by two defensive cubes with their arrow slits. The interior of the cubes is accessed by two spiral staircases. The upper brick body is an extension made by the Duke of Lerma in 1610 to serve as a prison. Today, it is the headquarters of the Regulatory Council of the Arlanza Denomination of Origin.
