Clam castle was built in 1149 by Otto von Machland who owned all of Upper Austria. At that time it was a fortress consisting of two towers over 30 meters high. These two impressive buildings, one round and one rectangular, still exist in the very same shape today.
Soon after Otto von Machland died, the castle fell into the hands of robber barons. They were feared by the people of Upper Austria and excommunicated by the church. During the middle ages the ownership and construction of the castle changed several times until in 1454 the forefathers of the counts of Clam arrived
During the 30 year-war the Clam family had their own private army to defend the castle. In these times of turmoil and revolts Clam village also suffered a lot and was burned down several times. Clam was besieged many times but no hostile troops ever managed to capture the castle. However, in the mid 17th century when the war was over, the castle was in a very bad condition.
Under the regency of Johann Gottfried of Clam it was possible to renovate the entire castle. He started to transform the functional fortress into a comfortable castle as we see it today. He also built a church, a hospital and water pipes for the citizens of the village.
In the 18th century the wings housing the administration, the coaches and the horse stables were built. Today these wings form the outer yard.
Fortunately Clam castle also survived both world wars unharmed. Only the nuclear shelter, built in one of the castle’s cellars is a reminder of the 20th century.
Besides the Castle the estate includes several farmhouses, a riding school, a hydropower plant, farmland and forests.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.
