Church of Sant Pere de Serrallonga Monument · Alpens, Lluçanès, Barcelona The church of Sant Pere de Serrallonga, or de Vilallonga, stands isolated at 1,041 metres altitude at the north-western end of the municipal district of Alpens; the name Serrallonga, taken from the neighbouring mas of the same name, replaced the original name of Vilallonga around the 13th-14th centuries, that name already documented in 938 and 982. It is a single-nave building with an almost square rectangular presbytery, closed by a horseshoe-profile triumphal arch, with the door opening onto the south wall. The population loss of the 14th century made it lose its status as an independent parish, remaining a subsidiary of Alpens until 1686. It preserves a painted wooden altar from 1627 and a plaster decoration with a mitred shield of the two keys of Saint Peter; reformed in 1724 and 1837, the sacristy, attached to the north side, and the present roof of Arab tiles date from this last year.
