Citania de Briteiros
Citania de Briteiros is an archaeological site in Portugal that contains the ruins of an ancient community from the 2nd century BC. Citania de Briteiros was home to a castro civilization, so termed because the high areas where they inhabited were referred to as "castros."
Visitors can see the ruins of an Iron Age hillfort as well as a cremation furnace today. At the visitor's center, there's also a modest museum of unearthed finds, as well as breathtaking views of the valley.
The settlement of Citania de Briteiros, built during the 1st and 2nd century BC, was built in an area known for rock art engravings during the Atlantic Bronze Age. As stones were cut to build family houses and protective fortifications, many of these engraved rock surfaces were destroyed. The Celts of the Castro culture lived in Citânia de Briteiros, where they built forts on hilltops and hid their valuables in rocky outcrops.
