The Roman Temple of Vic.
This temple was built in the second century, but was lost in time between the castle walls of the Moncada family. In 1882, demolishing the castle walls, which by then was a prison, it was discovered this treasure.
As I have explained some friends in town, the discovery was made from the window of the house across the street, which was the seat of a private organization protecting the heritage. To their surprise they were neighbors of a gem of more than 1600 years old.
This is the best preserved Roman temple in the Iberian Peninsula.
