Clervaux Castle dates back to the 12th century. The oldest parts of the castle were built by Gerard, Count of Sponheim, a brother of the Count of Vianden. The large palace and the rounded towers are probably from around 1400 when the prosperous Lords of Brandenbourg lived there.
In 1634, Claude of Lannoy built the reception halls, including the large Knights' Hall in the Spanish style of Flanders. In 1660, stables, storerooms and administrative buildings were added. Finally, in the 18th century, new stables were built.
Over the years, like other castles in Luxembourg, Clervaux fell into disrepair although it was partly restored and used as a hotel before it was finally destroyed in the Second World War during the Battle of Clervaux (December 16 to 18, 1944), part of the Battle of the Bulge.
After being fully restored after the war, the castle is now used partly as a museum and partly for housing the local administration. The south wing houses an exhibition of models of Luxembourg's castles, the old kitchen in the Brandenbourg House is a museum devoted to the Battle of the Ardennes while the upper floor house display photographs by Edward Steichen in an exhibition entitled The Family of Man. The remaining rooms are used for the services of the local administration.
It houses the commune's administrative offices as well as a museum containing an exhibition of Edward Steichen's photographs. The castle is open to visitors.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.
