Dun Ringill is an Iron Age hill fort on the Strathaird peninsula. Further fortified in the Middle Ages, tradition holds that it was for several centuries the seat of Clan MacKinnon. The original structure is consistent with an Iron Age Broch dating to approximately the first years of the common era. The main and subordinate structures have been occupied and modified throughout its history until the 19th century. Tradition relates that the structure was occupied by the MacKinnons as their clan seat well before the 16th century. It is mentioned in historical texts in the 16th century after which the MacKinnons moved their seat to Dunakin.
Dun Ringill today is a stacked stone ruin overlooking Loch Slapin. The present structure is approximately 4 meters in height and 16 meters on each side with a ditch following the outer wall. Its most notable feature is the central landward facing doorway approximately 1.8 meters high that leads into the center of the structure. The interior of the structure contained two rectangular buildings 4.5 meters by 2.4 meters. The original layout was similar to that of a broch, a form of complex Atlantic roundhouse.
A stone wall foundation encloses area adjacent to the structure. Similarly to other castles and fortified houses, the wall probably formed a defensive perimeter and livestock enclosure. The remains of the wall itself are hidden by vegetation. A site survey has shown that there are remains of other buildings in the immediate vicinity; and although their age is uncertain, it is likely their construction and occupation was throughout the history of Dun Ringill up until the 19th century.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.
