|Palazzo Pubblico built between the 13th and 14th centuries, continues in its ancient role as Siena's town hall and the Museo Civico is housed here. The facade is decorated with beautiful windows; inside are many halls, all frescoed by local artists, who in that time founded the Sienese School and left works of inestimable artistic value. In the palace courtyard is the entrance to the magnificent Torre del Mangia, the palace's huge bell tower. Rising 102 m (335 ft), it is a prominent feature of Siena's skyline. Built by the brothers Muccio and Francesco di Rinaldo between 1138 and 1148; there are 505 steps to the top of the tower with breathtaking views of countryside.
