St Mark's Basilica and Square, Venice

St Mark's Basilica, the cathedral of Venice, glitters inside with more than 8,000 square metres of gold mosaics. Highlights are the Pala d'Oro, a jewelled golden altarpiece, and the bronze horses in the museum upstairs, with access to the terrace over the square. Outside, the Piazza San Marco is Venice's great square, with the bell tower (campanile), which you can go up, and historic cafés such as Florian.
