Orsini stronghold a few years later. The sixteenth century was a period of splendour for Bracciano. The notorious spendthrift and libertine Paolo Giordano I Orsini, having married in 1558 Isabella de' Medici, daughter of Cosimo I, Grand Duke of Tuscany, received the title of duke of Bracciano in 1560. The castello received some modernization for the brief visit of the Medici that year. He hired the most prestigious painter available in Rome, Taddeo Zuccaro, to fresco with allegories and coats-of-arms the fortress's most prestigious room, the Sala Papalinia that had been occupied by Sixtus IV. Isabella spent the remainder of her life avoiding a return to the castle, which a modern tourist tradition would have her haunting. The economy was boosted by the exploitation of sulphur and iron, the production of tapestries and paper. The latter was favoured by the construction of an aqueduct whose ruins can still be seen in the city. Bracciano in this period had some 4,500 inhabitants. However, the expensive tenor of life of the Orsini eventually damaged the economic conditions of the city. The last great ruler was probably Paolo Giordano II, a patron of arts and literature who made Bracciano a center of culture in Italy. The decline culminated in 1696 when the castle was sold to Livio Odescalchi, nephew of Pope Innocent XI; the Odescalchi family still retain the castle. In the castle, richly frescoed friezes and ceilings now contrast with blank walls, which were hung with richly coloured tapestries when the lords of Bracciano were in residence. The important late-15th century frieze showing the labours of Hercules is still visible. The main economic activities are tourism, services and agriculture. Until the twentieth century the region was notoriously unhealthy for its malaria, now eradicated; as a result, none of the fine villas were built at the water's edge, but all stood on healthier rises of ground. Main sights The main monument of Bracciano is its castle, Castello Orsini-Odescalchi, one of the most noteworthy examples of Renaissance military architecture in Italy. outside the city, alongside the road leading to Trevignano Romano, is the ancient church of San Liberato (ninth century). It occupies what was once the Roman settlement of Forum Clodii, now surrounded by an herb garden, part of the complex of English-style gardens at the adjoining Villa San Librato, designed by Russell Page in 1965 for the art historian conte Donato Sanminatelli and
