Best ancient sites in Portugal

Portugal’s ancient sites belong mostly to Roman Lusitania, with a prehistoric layer older and further north. Conimbriga, south of Coimbra, is the largest and most rewarding: a walled town with baths, a forum and mosaic floors, where water still plays in the garden of the House of the Fountains. Ammaia lies in a quiet valley below the hilltop village of Marvao, Troia across the water from Setubal was a great fish-salting works, and Cerro da Vila sits beside the marina at Vilamoura. Older still are the Great Dolmen of Zambujeiro near Evora and Citania de Briteiros, an Iron Age hill town of round stone houses near Guimaraes.
