The town has as patrons San Blas and La Candelaria (2 and 3 February), chosen only by the coincidence of their festivity with the arrival, in 1574, of the royal procession carrying the mortal remains of Emperor Carlos I, on the way to the Monastery of El Escorial, reason why it is included in the so-called Imperial Route of the Community of Madrid.
