The castros were fortified enclosures, surrounded by moats and walls. Inside, the stone houses, with circular layouts and thatched roofs, were distributed in neighbourhoods, separated by streets and squares. Other longer constructions functioned as meeting or worship spaces, and some villages even had steam baths. The Castro de Santa Tecla, in the Galician town of A Guarda (Pontevedra), is a representative example, but there are more.
