Cathedral

Mosaics, skulls, crypts and biblical-meets-tropical imagery: Otranto's cathedral is like no other in Italy. It was built by the Normans in the 11th century, incorporating Romanesque, Byzantine and early Christian styles with their own, and has been given a few facelifts since. Covering the entire floor is its pièce de résistance, a vast 12th-century mosaic of a stupendous tree of life balanced on the back of two elephants.
