This gate was built in the late 18th century to provide access from the town to the monastery church.
The townsfolk who attended the services passed through the gate and entered the church via the north door. Churchgoers could continue as far as the west facade, where a great wall barred access to the south facade and the cloistered part of the monastery.
In the 16th century, the so-called “Carrera” area was the place where the stonemasons set up their workshop and, as Sonia Jiménez Hortelano pointed out in “La historia constructiva del Real Convento de Santiago de Uclés” (January 2019), it was still being used in the late 18th century for tasks related to the supply of building materials.
