The Calvary is a complex of sacral buildings all built in baroque style including several churches and chapels. It was built in 1715, but the 20th-century communist regime let its buildings decay. Thankfully, a fund was created to preserve this monument as it's been declared one of the 100 most endangered monuments in the world, as recognized by the World Monument Fund in New York.
Even if you have no interest in its historical value though, it's a lovely place to take a nice, longer walk and enjoy its park.
