Barcelona Spain, Gaudi Park Guell ~ when I first saw Gaudi's work in person I was over awed! I could have stayed at Parc Guell all day! Should be on anyone's top 10 list of places to visit in Barcelona!
The Garden of Oranges (Giardino degli Aranci). Look into the tiny keyhole of its green door to see the dome of St. Peter’s artistically framed in an arbor of greenery. People banging on the door if you stand in front of the keyhole, on the other side.
