Giotto’s Campanile is a free-standing campanile that is part of the complex of buildings that make up Florence Cathedral on thePiazza del Duomo. Standing adjacent the Basilica of Santa Maria del Fiore and the Baptistry of St. John, the tower is one of the showpieces of the Florentine Gothic architecture with its design by Giotto, its rich sculptural decorations and the polychrome marble encrustations. This slender structure stands on a square plan with a side of 14.45 metres (47.41 ft). It attains a height of 84.7 metres (277.9 ft) sustained by four polygonal buttresses at the corners. These four vertical lines are crossed by four horizontal lines, dividing the tower in five levels.
