Church of San Pedro, Becerril de Campos, Renaissance church and cultural center in Becerril de Campos, Spain.

San Pedro Cultural occupies the ruins of the 12th-century church of San Pedro in Becerril de Campos. The Romanesque portal, the oldest surviving element in the town, has archivolts carved with flowers and braids and two door leaves: one of contemporary corten steel, the other a Baroque-style replica. The roofless nave now holds a Foucault pendulum, sundials and a reconstructed vault painted with the sky.

The church of San Pedro was built in the 12th century; its Romanesque portal is the oldest surviving element in Becerril de Campos. After the rural exodus left the village with too many churches, it was deconsecrated and used as a school and granary, and grain pressure damaged the walls. Demolition of the tower in the 1970s destabilised the building, which became a total ruin within 40 years. Reconstruction began in 2013 under architects Juan del Olmo García, Carlos del Olmo García and Álvaro Gutiérrez Baños, and the astronomy-themed San Pedro Cultural opened on 19 March 2015.

The name San Pedro Cultural marks the change from parish church to astronomy centre, opened on 19 March 2015. Inside, a Foucault pendulum driven by an electromagnet swings continuously, and a beam of light crosses the meridian line on the floor, marking the months, the zodiac signs and the solstices. The apse keeps the Nicho de las Estrellas, medieval eight-pointed stars found under plaster during restoration.

The site is located on Calle San Pedro street and is accessible from the town center. Check ahead by phone or online for current opening hours and event schedules before planning your visit.

During restoration, plaster was removed from the apse and revealed medieval eight-pointed stars painted on the wall. The discovery surprised the team because it matched the astronomy theme of the project. The stars can be seen when visiting on 21 December, the winter solstice.
