10th century One of numerous towers is raised here as a defence against Saracen attacks -- the ancient name Castrum Brachiani implies it, and the castle's earliest history is inferred from it.
1050 In the eleventh century the Prefetti di Vico family acquire the neighbouring territory and turn the tower into a castle.
1234 Ferdinand Gregorovius dated the Orsini possession of Bracciano to this year. From 1375 it is a papal possession.
1419 The Colonna pope Martin V confirms the fiefdom of Bracciano in the Orsini branch of Tagliacozzo. Under them the town becomes flourishing and famous throughout Italy for its castle.
1470 Napoleone Orsini begins the enlargement that produces the present castle, to a design by Francesco di Giorgio Martini. His son Virginio completes it in 1485. Antoniazzo Romano paints much of the interior decoration.
1481 Sixtus IV, fleeing the plague in Rome, is received here; the Sala Papalina in one of the corner towers commemorates it, and the rooms he used are frescoed by Taddeo and Federico Zuccari.
1485 Papal troops under Prospero Colonna ravage the city and the castle. A new line of walls is built afterwards.
1494 Charles VIII of France stops at Bracciano with his troops on the march against Rome, and the Orsini are excommunicated for it.
1496 Alexander VI sends his son Giovanni di Candia with a papal army against the castle and the Orsini hold it. Cesare Borgia attempts the same a few years later and also fails.
1558 Paolo Giordano I Orsini marries Isabella de' Medici, daughter of Cosimo I, and receives the title duke of Bracciano. The family's lavish living will eventually tell on the city's finances; Paolo Giordano II, patron of arts and letters, is probably the last great ruler.
1696 The decline ends in a sale: the castle goes to Livio Odescalchi, nephew of Pope Innocent XI, whom Leopold I makes a Prince of the Holy Roman Empire for services against the Turks. The family still retain it.
1798 After the French occupation the castle is looted of its valuable furniture. It passes to Duke Marino Torlonia until 1848, when it is sold to Prince Livio Odescalchi III.
1952 Prince Livio Odescalchi IV opens the historical museum inside the castle.

Checked against Wikipedia — The castle's earliest history is inferred to be linked to one of the numerous towers built in the tenth century as a defence against Saracen attacks, as implied by the ancient name of Castrum Brachiani; in the eleventh century the neighbouring territory was acquired by the Prefetti di Vico family, who turned the tower into a castle. Ferdinand Gregorovius dated the possession of Bracciano by the Orsini to 1234, and from 1375 it was a Papal possession, In 1419 the Colonna Pope Martin V confirmed the fiefdom of Bracciano in the Orsini family branch of Tagliacozzo, and under this powerful family Bracciano developed into a flourishing town famous in the whole of Italy for its castle, which was enlarged starting from 1470 by Napoleone Orsini and his son Virginio; in 1481 it hosted Pope Sixtus IV who had fled the plague in Rome, the Sala Papalina in one of the corner towers commemorating the event, and four years later the city and castle were ravaged by Papal troops under Prospero Colonna, after which a new line of walls was built, Construction of the Orsini-Odescalchi Castle was started by Napoleone Orsini in 1470 and completed by his son Virginio in 1485, with Francesco di Giorgio Martini as architect; in 1494 Charles VIII of France and his troops marching against Rome stopped at Bracciano, an act that led to the excommunication of the Orsini, and in 1496 Pope Alexander VI's son Giovanni di Candia led a papal army and tried to capture the castle but the Orsini successfully resisted, while Cesare Borgia was unsuccessful in his attempt a few years later, During this time the castle underwent modifications with many interior decorations created in the form of paintings and frescoes by Antoniazzo Romano, a Roman painter and sculptor of the 15th century, and the rooms where Pope Sixtus IV stayed were decorated with frescoes by the Taddeo Zuccari and Federico Zuccari brothers, In 1558 Paolo Giordano I Orsini, marrying Isabella de' Medici daughter of Cosimo I, received the title of duke of Bracciano, but the lavish life of the Orsini family eventually affected 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 centre of culture in Italy, and the decline culminated in 1696 when the castle was sold to Livio Odescalchi, nephew of Pope Innocent XI, the Odescalchi family still retaining it. Emperor Leopold I gave Livio the honorific of Prince of the Holy Roman Empire for services in the war against the Turks; after the French occupation the castle was looted of its valuable furniture, and the castle and estate were under Duke Marino Torlonia until 1848 when they were sold to Prince Livio Odescalchi III, The historical museum within the castle premises has valuable artwork from the Middle Ages of over six centuries of rule by Popes and Kings, consisting of ancient weapons, furniture and paintings, books and manuscripts, frescoes and decorations, and was opened in 1952 by Prince Livio Odescalchi IV (October 2026).
