Piera is a municipality covers a large portion of the southeastern corner of the comarca of Anoia in Catalonia, Spain, on the left bank of the Anoia river. The agricultural land, mostly non-irrigated, is used for the cultivation of cereals, grapes, olives and almonds. The town itself hosts a number of light industries: textiles, plastics and construction materials. Tourism during the summer months is also relatively important for the local economy. Another Piera relevant monument is the church of Santa Maria, with both gothic and roman elements
