Citânia de Santa Luzia

The Citânia de Santa Luzia is an archaeological site of the Castro culture located in the Portuguese civil parish of Areosa in the municipality of Viana do Castelo. Its construction dates from the Iron Age, and it shows evidence of occupation during the Roman period. The Castro was first dug in 1876 by Joaquim Possidonio Narciso da Silva. Only about one third of the structures have been dug, with the remaining part being under or destroyed during the construction of the nearby hotel, church, and respective roads. The site also included a possibly medieval chapel dedicated to Saint Lucy which persisted, after some reconstructions, until 1926 when it was destroyed to give way to the Saint Lucy Church of Miguel Ventura Terra.
