The Church of San Bartolomé, better known as the Hermitage of El Cerrillo, was built in 1447. Its construction was financed through a donation of 1,000 maravedis from the Marquis of Santillana. Due to its poor condition in the late 17th and early 18th centuries, it was rebuilt with granite stone. The final necessary renovation was carried out in the 20th century. Currently, the Galapagar pilgrimage is celebrated on the second Sunday in May in honor of Our Lady of the Forsaken.
