Church of Santa Marina de Balboa Monument · Balboa, El Bierzo, León The church of Santa Marina stands in the valley of the Balboa river, in the Valcarce comarca, where pallozas are still preserved, in a municipality whose first written mention appears in a donation that Bermudo II made to the monastery of Samos in the year 988. A temple of Romanesque origin reworked in Renaissance style, it was declared Bien de Interés Cultural (Spain's highest level of heritage protection) on 3 June 1993. Its original fabric, with a single nave and a chancel with a semicircular apse preceded by a straight bay, was built in the 12th century or the early 13th; in the 16th century the structure was altered and the tower begun, and between the 17th century and the early 18th it took on its present form. It was restored between 2005 and 2006, and its high altarpiece in 2010. Photo: Rodelar (CC BY-SA 3.0) What to see and do in Balboa
