Church of Nuestra Señora de la Asunción de Pisón Monument · Castrejón de la Peña, Montaña Palentina, Palencia The church of Nuestra Señora de la Asunción, in Pisón de Castrejón, is a Romanesque church in ashlar stone, declared a Bien de Interés Cultural (Spain's highest level of heritage protection) on 11 February 1993. Its portal, which projects from the wall, is formed by four columns supporting pointed archivolts decorated in honeycomb pattern, above which runs a string course with the twelve apostles and the Pantocrator at the centre; the porch that shelters it rests on octagonal columns with carved capitals. The outer apse displays corbels with plant and animal motifs, and inside a Gothic relief of the Mass of Saint Gregory is preserved. At the foot of the church, above the gable, rises a three-tier bell-wall, each tier with a double bell arcade, topped with a Baroque finial of balls.
