Roman Villa of Alto da Cidreira

A Roman villa in Alcabideche, Cascais, known since the 1890s but not systematically excavated until 1980-1981 by archaeologists Guilherme Cardoso and Jose d'Encarnacao. The site comprises a manor house with a thermal complex (baths), remains of mosaics, and an olive oil mill. Terra sigillata ceramics indicate primary occupation in the late 1st to early 2nd century AD, with abandonment in the late 2nd-3rd century and reoccupation in the 4th-5th century. Notable finds include a small terracotta mask representing an African head, now displayed in the Condes de Castro Guimaraes Museum in Cascais. Classified as Imovel de Interesse Publico since 1992.
