The Abbey of Saint Gall has existed at least since 747 AD and became an independent principality between 9th and 13th centuries, and was for many centuries one of the chief Benedictine abbeys in Europe. The Abbey of St Gall is an outstanding example of a large Carolingian monastery and was, since the 8th century until its secularisation in 1805, one of the most important cultural centres in Europe. The library at the Abbey is one of the richest medieval libraries in the world. Since 1983 the whole remaining abbey precinct has been a UNESCO World Heritage Site.
Around 613 Gallus, according to tradition an Irish monk and disciple and companion of Saint Columbanus, established a hermitage on the site that would become the monastery. Following Gallus' death, Charles Martel appointed Othmar as custodian of St Gall's relics. Several different dates are given for the foundation of the monastery in the middle of the 8th century. Othmar founded the Carolingian style Abbey of St Gall, where arts, letters and sciences flourished. The abbey grew fast and many Alemannic noblemen became monks. Under abbot Waldo of Reichenau (740–814) copying of manuscripts was undertaken and a famous library was gathered. The abbey became an Imperial Abbey (Reichsabtei) by Emperor Louis the Pious in 813.
From this time until the 10th century, the abbey flourished. It was home to several famous scholars. During the 9th century a new, larger church was built and the library was expanded. Manuscripts on a wide variety of topics were purchased by the abbey and copies were made. Over 400 manuscripts from this time have survived and are still in the library today.
On 26 April 937 a scholar kindled a fire and the abbey and the adjoining settlement were almost completely destroyed; the library was however undamaged. About 954 they started to protect the monastery and buildings by a surrounding wall. In the 13th century the abbey became more involved in local politics and entered a period of decline.
In the 16th century the abbey was raided by Calvinist groups, which scattered many of the old books. In 1530, abbot Diethelm began a restoration that stopped the decline and led to an expansion of the schools and library. Under abbot Pius (1630–74) a printing press was started. In 1712 during the Toggenburg war the Abbey of St. Gall was pillaged by the Swiss.
Following the disturbances, the abbey was still the largest religious city-state in Switzerland, with over 77,000 inhabitants. A final attempt to expand the abbey resulted in the demolition of most of the medieval monastery. The new structures, including the cathedral by architect Peter Thumb (1681-1766), were designed in the late Baroque style and constructed between 1755 and 1768. The large and ornate new abbey did not remain a monastery for very long. In 1798 the Prince-Abbot's secular power was suppressed, and the abbey was secularized. The monks were driven out and moved into other abbeys. The abbey became a separate See in 1846, with the abbey church as its cathedral and a portion of the monastic buildings for the bishop.
The Abbey of St. Gall largely got its present appearance in the 18th century. It is an impressive architectural ensemble comprising different buildings regrouped around the main square of the abbey: The west side includes the ancient abbatial church (the present cathedral), flanked by two towers and the ancient cloister, which today houses the abbatial Library; located on the east side is the “Neue Pfalz”, the present seat of the canton authorities. The northern part of the square is composed of buildings of the 19th century: the ancient arsenal, the Children’s and Guardian Angels’ Chapel and the former Catholic school.
The High Baroque library represents one of the most beautiful examples of its era, and the present cathedral is one of the last monumental constructions of Baroque abbatial churches in the West. In addition to the architectural substance, the inestimable cultural values conserved at the Abbey are of exceptional importance, notably: the Irish manuscripts of the 7th and 8th centuries, the illuminated manuscripts of the St Gall School of the 9th and 11th centuries, documents concerning the history of the origins of Alemannic Switzerland as well as the layout of the convent during the Carolingian era (the only manuscript plan of that time remaining worldwide, conserved in its original state, representing a concept of monastic organisation of the Benedictine order).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.
