Castro de Coaña, Spain
Castro de Coaña was the first fort studied in Spain. The fort dates from the Celt-Roman era although there was probably a settlement here during the Iron Age. It was excavated in 1877 by José María Flórez and after the Civil War various interventions were undertaken. The evidence of circular rather than rectangular housing or burial without the use of ash urns make the Castro not have a direct relationship with the Celts.
This was one of the few sites mentioned in our guide book of Spain. It is a nice site although it has been a bit over restored. There is a small charge to enter but there is facilities there including a good visitors centre.
