During excavations at Slotsbanken, proof was found that people had resided there in the 10th century. However, this may not have been in connection with a castle or other building, but historical sources indicate that a castle was situated here in the early 1200s. It was a royal castle with a bailiff, who looked after the King’s interests in the area, collecting taxes from the townsfolk. The bailiff, later called a vassal, was responsible for a geographic area, a so-called fief and Riberhus fief included most of West Jutland up to Nymindegab. One of the best-known vassals of the castle was Albert Skeel, who was buried in Ribe Cathedral. Albert Skeel was vassal under King Christian IV in the 1600 years.
It is unknown how the castle looked originally, but archaeological excavations indicate that the castle consisted of a number of built together houses, surrounding a yard and round towers with canons in every corner for defense. Thick walls and the moat made it hard for trespassers to get into Riberhus. You had to pass the drawbridge and gatehouse in order to get into the castle. In 1400, Ribe was getting poorer and the number of citizens was decreasing, due to several pest epidemics. Copenhagen became capitol of Denmark and Riberhus declined, since there was no activity there anymore. After the Swedish Wars in 1600, the buildings were in such a bad state that the castle was torn down.
Today, you can see a statue of Queen Dagmar, who was married to King Valdemar Sejr on Slotsbanken. Dagmar died in the age of 23 on Riberhus and the statue shows her in front of a boat, sailing to Ribe. The artist Anna Marie Carl-Nielsen, created the statue in 1913 in memory of the young queen. The ruins at Slotsbanken were restored in 1940-1941, where the moats were cleaned and filled up with water, like in the days of glory. Slotsbanken was at the same time restored to its original look; about 8 meters high and over an area of 90x90 meters. The remaining ruin is administrational building.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.
