The Museum of Palencia is located in the Casa del Cordón, the only civil monument from the 16th century in Renaissance style that can be seen today in the city. The palace was commissioned as a residence in the city by Francisco Núñez de Paz, lawyer, rapporteur of the Royal Council of Castile, attorney and business agent of Hernán Cortés in Spain, and his wife Isabel Rodríguez Monroy, from Palencia. The most notable element of the palace is the façade, which features the coats of arms of the promoter family. The façade is framed by a semicircular arch and a Franciscan cord carved like an alfiz that gives its name to the palace.
The building was rehabilitated and expanded in the 80s of the last century in an interesting project by architect Luis Arranz. The museum distributes its collections over two floors and a basement with several rooms that bring together an excellent collection of pieces that cover Prehistory (through a selection of objects found in sites such as Los Llanos, La Velilla, La Huelga, Paredes de Nava or Monte Bernorio), the Celtiberian Culture (thanks to a sample of weapons, jewels and utensils left by the Vaccean and Cantabrian peoples), Roman Hispania (among whose treasures the mosaic of Oceanus and the Nereids found in the thermal baths of Villa Possidica, Dueñas) and the Middle Ages.
