32km/20mi north of Palencia on N 611, just beyond the Canal de Castilla, is Frómista, which was an important staging-point for pilgrims on the Way of St James. Its most notable monument is the brick-built church of San Martín (1066), which belonged to an 11th century Benedictine monastery. It is a magnificent example of Spanish Romanesque
architecture, with two round towers on the plain west front and an octagonal tower over the crossing. The church of Santa María has a large 15th century retablo.
