Church of la Asunción de Nuestra Señora de Cea Monument · Cea, Sahagún, León The church of the Asunción de Nuestra Señora de Cea, known as the new church, was designed by the architect Julio del Campo and construction began in 1909 next to Cea Castle, using stones from the castle itself among the building materials. It was funded by doña Margarita de Modino, a wealthy resident who died without heirs in 1908 and left her fortune to build it. The building replaced the old church of San Martín as the main parish church, which still stands in the same town centre. Photo: Rodelar (CC BY-SA 4.0) What to see and do in Cea
