Torre dell'orologio, Venice

Torre dell'orologio is the clock tower marking the entrance to the Merceria from Piazza San Marco. Its monumental arch carries the street between Venice’s ceremonial square and the Rialto trading district, while the tower and its adjoining lower buildings form a single architectural composition. The design is attributed to Mauro Codussi and belongs to Renaissance architecture.

Construction took place from 1496 to 1499, with later additions in 1506 and 1757. The clock was deliberately placed where it could be seen from the lagoon, turning timekeeping into a public display of Venetian power. Look at the great dial: its face combines a sun pointer, the earth, the moon, fixed stars, and zodiac signs dating from the 1490s.

Above it, the Virgin and Child occupy a curved gallery, with hour and minute panels on either side. Higher still, two massive bronze figures strike the bell; their darkened surface gives them the familiar name “the Moors.” The bell itself was cast by Simeone Campanato at the Arsenal in 1497.

On the terrace below the figures, the winged Lion of Saint Mark appears with an open book against a blue, starry field. On the feast of Epiphany and Ascension Day, the Magi once emerge in procession to bow before the Virgin and Child.
