Covarrubias owes its name to the reddish caves that abound in its outskirts. The city centre, where there are remains of the old wall, is a wonderful example of typical Castilian urban layout: arcaded streets and houses that have wooden structures.
We must mention the large tower de Doña
Urraca (Mrs. Magpie's), a Mozarab work from the late 10th century,
and the old collegiate church of San Cosme and San Damián.
Under the altar lie the remains of three abbess-princesses, and
in the presbytery, those of Count Fernán González
and his wife Sancha, the latter buried in a 4th-century Roman-Spanish
sarcophagus. The cloister dates from the 16th century, and the
museum, which the visitor should not miss, keeps one of the most
beautiful Gothic-Flemish images: a 16th-century triptych of the
Adoration of the Magi.
