The Plaza Mayor (Main Square) is opposite the main façade of the palace. At night, the lights of the Parador make it look even more magnificent and stately. The medieval quarter, Arch, Cárcel Bridge, San Blas Convent, Santo Domingo Monastery, Pasadizo del Duque (Duke's Passage) and former collegiate church of San Pedro are just some of the treasures you won't want to miss.
The area around Lerma is well worth a visit. 22 kilometers away is Covarrubias, a lovely village where San Cosme y San Damián Collegiate Church and Doña Sancha and Doña Urraca squares invite travelers to enjoy a leisurely visit, imagining that time has stood still in the Middle Ages and that little has changed since the year 987, when Count Fernán González founded the town.
About half an hour away by car is another treasure: the Monastery of Santo Domingo de Silos, a Romanesque jewel which has become a place of spiritual and artistic pilgrimage. It is also not far to beautiful Aranda de Duero, city of wine, monuments, history and culinary expertise.
