The Archivo del Adelantamiento de Castilla in Covarrubias

The Archivo del Adelantamiento de Castilla is a building in the town of Covarrubias, in the province of Burgos (Castilla y León). It was constructed in the second half of the 16th century and restored in 1963, built into the walls which served as its north gate and buttress. In the mid-18th century, the remaining traces of those walls disappeared.

The building was declared a monument of historic-artistic interest on July 13, 1961, and currently holds the status of a good of cultural interest. It is also included within the area delimited as a good of cultural interest in the category of historical complex of the town.

It has the shape of a stone prism with a rectangular base, three heights with Renaissance windows, notable ironwork, a large shield in the center, and buttresses at the corners and next to the entrance arch. The design and project are attributed to Juan de Herrera, with execution by Juan de Vallejo, who contributed plateresque details.
