This card is from Barcelona, Spain (somewhere I've actually visited). This is the Bridge of the Enamored Ones (Puente de los enamorados) in the Park Guell. This is one of my favorite cities around the world and the Park Guell is excellent. It has some very interesting art work in it by Antonio Gaudi -- a lot of colorful mosaics and architecture.
Thanks amapola11 for the card (ES-94400).
