The Torremocha Castle represents the history and monumentality of Santorcaz. The current construction dates back to the 14th and 15th centuries. It was a fortress for the defence and control of the Anchuelo river plain, built on a previous watchtower of Arab origin that formed part of the strategic line of the Alcalá stronghold. At different times it has been the residence of nobles, the seat of archbishops and a prison for clerics, where Cardinal Cisneros and the Princess of Éboli were among others. Attached to the castle walls is the church of San Torcuato, founded in the 13th century, with a beautiful Mudejar tower.
