Casa dos Nichos is a 15th-century building. Having undergone renovations to create an exhibition area, one can now visit and see part of the county’s archaeological estate. The items on display are from Prehistory, the Iron Age and Romanization. Heavily oriented by a pedagogical vocation, visitors can utilize a wide range of multimedia tools to access information regarding local heritage such as Citânia of Santa Luzia (Santa Luzia settlement), the medieval tombs of Santa Maria de Geraz do Lima or the rock engravings of Carreço.
