Dingwall Castle is believed to have been established by Norse settlers in the area in the 11th century. During the Wars of Scottish Independence the castle was garrisoned by the forces of king Edward I of England. However it was later captured by Scottish forces for king Robert I of Scotland (Robert the Bruce) led by Uilleam II, Earl of Ross.
From the castle, the Earl of Ross (chief of Clan Ross) led the men of Ross to fight against the English at the Battle of Bannockburn in 1314. As a reward in 1321 King Robert granted Dingwall Castle with the town and lands of Dingwall to the Earl of Ross.
In 1370 a feud arose between William de Moravia, 5th Earl of Sutherland (chief of Clan Sutherland) and Aodh Mackay (chief of Clan Mackay). A meeting was arranged for them to meet at Dingwall Castle to resolve their issues. However Aodh Mackay and his son Donald Mackay were both murdered in the castle while they were asleep by Nicholas Sutherland, brother of the Earl of Sutherland.
In 1411 Domhnall of Islay, Lord of the Isles (chief of Clan Donald) captured Dingwall Castle as part of his attempt to seize the title of the Earldom of Ross. This took place shortly before the Battle of Harlaw. In 1438 the next successive Clan Donald chief, Alexander of Islay, Earl of Ross was officially recognised as the Earl of Ross and took up his residence at Dingwall Castle. His son, John of Islay, Earl of Ross was not as successful; the Earldom of Ross was confiscated from him and the castle became a royal possession once more in 1475. John Munro, 11th Baron of Foulis was then made governor of the castle, who in turn was succeeded by Andrew Munro, 2nd of Milntown. The next governor in 1488 was Sir James Dunbar.
In 1507 Andrew Stewart, Bishop of Caithness carried out improvements after the castle had been assaulted by the MacDonalds and Mackenzies. The Crown abandoned Dingwall Castle in about 1600 and it eventually fell into a ruin. The castle ceased to be maintained after the death of king James VI of Scotland in 1625. It was used as a quarry until 1817 when it was finally levelled and only a few fragments remain.
A tunnel still exists that runs from the site of Dingwall Castle to the basement of nearby Tulloch Castle. The tunnel has now collapsed, but it is possible to view this passageway through an air vent on the front lawn of Tulloch Castle's grounds.References:
The Palazzo Colonna is a palatial block of buildings built in part over ruins of an old Roman Serapeum, and has belonged to the prestigious Colonna family for over twenty generations.
The first part of the palace dates from the 13th century, and tradition holds that the building hosted Dante in his visit to Rome. The first documentary mention notes that the property hosted Cardinal Giovanni and Giacomo Colonna in the 13th century. It was also home to Cardinal Oddone Colonna before he ascended to the papacy as Martin V (1417–1431).
With his passing, the palace was sacked during feuds, and the main property passed into the hands of the Della Rovere family. It returned to the Colonna family when Marcantonio I Colonna married Lucrezia Gara Franciotti Della Rovere, the niece of pope Julius II. The Colonna"s alliance to the Habsburg power, likely protected the palace from looting during the Sack of Rome (1527).
Starting with Filippo Colonna (1578–1639) many changes have refurbished and create a unitary complex around a central garden. Architects including Girolamo Rainaldi and Paolo Marucelli labored on specific projects. Only in the 17th and 18th centuries were the main facades completed. Much of this design was completed by Antonio del Grande (including the grand gallery), and Girolamo Fontana (decoration of gallery). In the 18th century, the long low facade designed by Nicola Michetti with later additions by Paolo Posi with taller corner blocks (facing Piazza Apostoli) was constructed recalls earlier structures resembling a fortification.
The main gallery (completed 1703) and the masterful Colonna art collection was acquired after 1650 by both the cardinal Girolamo I Colonna and his nephew the Connestabile Lorenzo Onofrio Colonna and includes works by Lorenzo Monaco, Domenico Ghirlandaio, Palma the Elder, Salviati, Bronzino, Tintoretto, Pietro da Cortona, Annibale Carracci (painting of The Beaneater), Guercino, Francesco Albani, Muziano and Guido Reni. Ceiling frescoes by Filippo Gherardi, Giovanni Coli, Sebastiano Ricci, and Giuseppe Bartolomeo Chiari celebrate the role of Marcantonio II Colonna in the battle of Lepanto (1571). The gallery is open to the public on Saturday mornings.
The older wing of the complex known as the Princess Isabelle"s apartments, but once housing Martin V"s library and palace, contains frescoes by Pinturicchio, Antonio Tempesta, Crescenzio Onofri, Giacinto Gimignani, and Carlo Cesi. It contains a collection of landscapes and genre scenes by painters like Gaspard Dughet, Caspar Van Wittel (Vanvitelli), and Jan Brueghel the Elder.
Along with the possessions of the Doria-Pamphilij and Pallavacini-Rospigliosi families, this is one of the largest private art collections in Rome.
