Heilsbronn Abbey was a Cistercian monastery at Heilsbronn founded in 1132–33 by Saint Otto of Bamberg. It was settled by monks from Ebrach Abbey, under the first abbot Rapotho. It was one of the wealthiest monasteries of Germany, with possessions around Franconia as far as Regensburg and in Württemberg. These rich endowments were mostly made by the dukes of Abenberg and their heirs, the Hohenzollern Burgraves of Nuremberg. It was the hereditary burial-place of the Hohenzollern family and ten burgraves of Nuremberg, five margraves and three electors of Brandenburg, besides many other persons of note, were buried here.
Heilsbronn was a flourishing monastery until the time of the Reformation. In 1530 Abbot John Schopper (1529–1540) founded a monastic school here, which later became a Protestant school for princes, and the doctrines of Luther gradually found favour in the monastery. His successor, Sebastian Wagner, openly supported Protestantism. He married and resigned in 1543. In 1549 Roman Catholicism was restored at Heilsbronn, but only ostensibly, and the abbey seems to have ceased to be a Catholic house in 1555, although it existed for some years longer. The last abbot who made any pretense to Catholic belief was Melchior Wunderer (1562–1578). The five succeeding abbots were Protestants, and in 1631 Heilsbronn ceased to be an abbey. Its valuable library was transferred to Erlangen.
The buildings of the monastery have mostly disappeared, with the exception of the fine church, known as Münster Heilsbronn, a Romanesque basilica, restored between 1851 and 1866, and possessing paintings by Albrecht Dürer.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.
