A beautiful and pleasant Castilian-style square.

It is part of the so-called black villages of the Ayllón Mountains, so called because of the colour of the buildings, mainly built of black stone and slate, a material that is abundant in the region and on which the village is built.

Typical Castilian square with arcades from the late 19th century. In the middle there is a sand square that looks like a bullring. In the center is the town hall in front of the church Nuestra Señora del Manto. It is the center of the beautiful town and has many restaurants and bars with terraces.

Beautiful arcaded square. I recommend stocking up on artisanal bread and pastries at the bakeries in the square. There are also good places to have a tortilla skewer
