Chaves, in the North of Portugal, has always been know for its thermal waters, especially during the Roman Empire. And, when the city planned an underground garage it got a real surprise - Roman baths buried in a landslide some 1,700 years ago. Excavation are being done, with a museum projected to open in 2018.
Archeologists say an earthquake caused the collapse of the spa building leaving its contents "frozen in time."
It was a building of "monumental dimensions" that collapsed after an earthquake near the end of the fourth century.
Human remains were found as well as two large pools and seven small individual pools. In the ruins were many personal items such as rings, bracelets and objects in well preserved condition because because of the wet soil. Infant, excavations were slowed by the natural flow of thermal waters.
The site and a new museum should open in 2018.
