Knuthenborg is a manor house originally known as Årsmarke. It was first mentioned in 1372 and owned by the Urne family from 1527. Under King Frederick III, Cornelius Pederson Lerche was granted ownership of the estate in 1667. In 1677, his daughter Sister Lerche married the Mecklenberg nobleman Christoffer von Knuth who, on inheriting Aarsmarke, did much to improve it through extensions and increased prosperity. In 1714, their son Adam Christoffer von Knuth was elevated to the status of a count under Frederick IV which resulted in the change of name of the estate to Knuthenborg.
An older residence was still standing when the current structure was under construction. Today's manor house, also known as Enkesædet, was built by the architect Henrik Steffens Sibbern in 1866 in the Victorian style and was extended in 1886. A tower of French design with a pointed spire crowns one of its corners. Several other interesting buildings on the estate were built by Sibbern in the 1860s and 1870s, all with distinct appearances and features. Egehuset (the Oak House) in the Swiss style looks a little like a Tyrolean chalet. Flinterhuset (the Flint House), built literally in flint, is the most elaborate building with many fireplaces and chimneys true to the English tradition. The imposing Godsforvalterboligen (Forest Superintendent’s Residence) is accessed through the corner tower. Sibbern also built Maglemerporten, the majestic main gatehouse and porter's residence while Vilhelm Tvede (1826–1891) added the gatehouses at Snapind.
Eggert Knuth (1838-1874) called upon the English landscape architect Edward Milner to lay out the park in the late 1860s, creating artificial lakes fed by streams running through the estate. Nils Stenson was then working as the Chief Landscape Gardener to the Count of Kunthenborg. His son, Herman Stenson, who was assisting his father as a young boy and grew up in the estate's Hunting pavilion, had also made very lovely drawings of the Kunthenborg palace and the garden. Eggert Knuth died in 1870 at the young age of 36, when the basic layout had been completed as can be seen from a relatively simple map dated 1881. Many of the finer details from Milner's original design were missing but today's garden nevertheless reflects his general concept. Adam V. Knuth who succeeded Eggert added the fanciful ruin near the main entrance, typical of the follies in English gardens of the times. In 1926, the park was the first of its kind to be listed. As a result it was opened to visitors and further developed, especially, with large displays of rhododendrons. In addition to beech, there are oak, poplar, and coniferous trees, and a Sequoia gigantea.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.
