The Sparrenburg castle in Bielefeld was erected sometime before 1250 by the counts of Ravensberg. It guarded the Bielefeld Pass over the Teutoburg Forest, as well as acting as the ruling seat of the counts of Ravensberg, and as protection for the city of Bielefeld, probably founded around 1200. Because the construction of a protective castle generally predates the foundation of a town, it is assumed that there was an older castle. In 1256, the castle was first mentioned in records.
Following the discovery of gunpowder and the resultant increasing use of cannon and other firearms, dukes of Cleves (the counts of Ravensberg, the) ordered the expansion of the castle into a fortress of the Early Modern Period that could withstand bombardment from siege guns and also employ its own cannon. Around 1530, a round bastion was added in the west, only accessible from the castle itself via a bridge, from which one could control Bielefeld Pass with artillery. The construction was finished in 1578 and created the largest fortress in Westphalia. The old castle was now surrounded by a terrace and a high defensive wall.
After the War of the Jülich Succession the castle was granted to Dutch confederates. Their occupation became effective in November 1615.
In 1623, in the course of the Thirty Years' War, the Dutch had to retreat before the overpowering advance of the Spanish army. In 1625, Brandenburg's colonel Gent unsuccessfully attempted to reconquer the Sparrenburg with the help of Ravensberg's peasants. In 1636 the Swedes and Hessians besieged the Spanish for nearly one year before they had to hand over the fortress in 1637. In 1642, they left Sparrenburg to their French allies.
In 1648, the Peace of Westphalia confirmed the affiliation to Brandenburg-Prussia. In the following years the Grand Elector Frederick William stayed several times at the fortress, and two of his children were born there.
During the Franco-Dutch War the Sparrenburg successfully resisted its last sieges, in 1673 against troops of Münster and in 1679 French troops.
At the end of the 17th century, the Sparrenburg no longer met the military requirements. Therefore, it was partly used as a prison, and partly subjected to decline. The outer walls were torn down by agreement of King Frederick II of Prussia and were used for the construction of the barracks 55, which still stands at the Hans-Sachs-Straße.
Used as a anti-aircraft emplacement during World War II, the Sparrenburg was heavily damaged in the course of the air raid on Bielefeld on 30 September 1944; only the tower remained undamaged. From 1948 to 1987 there was continuous cleanup and restoration work. From 1955 to 1983 the German Museum of Playing Cards was housed in the rebuilt estate building. A new visitor center was opened in 2014. The above-ground parts of the Sparrenburg can be visited year-round, free of charge. The rest of the castle can be visited daily from April to October.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.
