Engelsberg Ironworks in Västmanland was constructed in 1681 and developed into one of the world's most modern ironworks in the period 1700-1800. The property comprises the mansion and park, works offices, workers' homes, and industrial buildings. Engelsberg is the only ironworks in Sweden that still preserves the buildings and most of the technical equipment. Engelsberg Ironworks was inscribed on the World Heritage List in 1993.
Iron production at Engelsberg goes back to the Middle Ages, when mine-owning farmers achieved efficiency in the use of the natural riches of the Bergslagen area. It was in the 18th century, however, that Engelsberg could definitely be ranked among the most important ironworks in Sweden and Europe. The works, which was ultramodern for its time, extracted and worked iron. The ore came from the Bergslagen mines, while the charcoal, which was crucial for heating the material, came from nearby forests.
Engelsberg Ironworks eventually consisted of about fifty different buildings. Besides the log-insulated smelting house and the hammer forge there is also a weighing house where the charcoal and ore were weighed. In the day workers' building, or the "inn" as it was also called, those who worked by the day could buy spirits and find accommodation. In 1917 a Lancashire forge with a rolling mill was built. The property also comprises two works offices, the gardener's house, slagstone towers, the grain store, workers' housing, and the byre. Engelsberg Ironworks is largely preserved as it looked after the last rebuilding in 1870. Particularly unique features are the blast furnace and the forge where the waterwheel, crusher, blower, and hammer still work.
For most of the eighteenth century Engelsberg Ironworks was owned by the Söderhielm family and in the nineteenth century by the Timm family. The works was sold in 1916 to Consul General Axel Ax:son Johnson, who put it under the administration of Avesta Ironworks. Three years later operations ceased. Engelsberg Ironworks is now owned by Nordstjernan AB, who restored the property in the 1970s with the aid of the National Heritage Board. In summer Engelsberg Ironworks is open to the public.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.
