53. Sant Romà de Sau, Spain
San Romà de Sau is a little village in Catalonia’s Osona region. It is totally submerged by the water of the Sau dam. This place once had a bridge, homes, and even a nice Romanesque church.
The best time to visit is when the reservoir is not filled to capacity. It is then that you can see the church’s bell tower emerging from out of the water. Mind you, if you get there during a drought you can visit the ruins of the entire village because there is no water there at all.
