The Hotel Tassel is a town house built by Victor Horta in Brussels for the Belgian scientist and professor Emile Tassel in 1893–1894. It is generally considered as the first true Art Nouveau building, because of its highly innovative plan and its groundbreaking use of materials and decoration. Together with three other town houses of Victor Horta, including Horta's own house and atelier, it was put on the 'UNESCO World Heritage List' in 2000.
The first town house built by Victor Horta was the Maison Autrique. This dwelling was already innovative for its application of a novel 'Art Nouveau' decorative scheme that didn't include references to other historical styles. However the floor plan and spatial composition of the Maison Autrique remained rather traditional. On the deep and narrow building plot the rooms were organised according to a traditional scheme used in most Belgian town houses at that time. It consisted of a suite of rooms on the left side of the building plot flanked by a rather narrow entrance hall with stairs and a corridor that led to a small garden at the back. From the three room suite only the first and the last had windows so that the middle room (mostly used as a dining room) was rather gloomy.
At the Hôtel Tassel Horta definitively broke with this traditional scheme. In fact he built a house consisting of three different parts. Two rather conventional buildings in brick and natural stone — one on the side of the street and one on the side of the garden — were linked by a steel structure covered with glass. It functions as the connective part in the spatial composition of the house and contains staircases and landings that connect the different rooms and floors. Through the glass roof it functions as a light shaft that brings natural light into the centre of the building. In this part of the house, that could also be used for receiving guests, Horta made the maximum of his skills as an interior designer. He designed every single detail; doorhandles, woodwork, panels and windows in stained glass, mosaic flooring and the furnishing. Horta succeeded in integrating the lavish decoration without masking the general architectural structures.
The innovations made in the Hôtel Tassel would mark the style and approach for most of Horta's later town houses, including the Hôtel van Eetvelde, the Hôtel Solvay and the architects own house and atelier. It might be superfluous to mention that these houses were very expensive and only affordable for the rich bourgeoisie with an Avant-Garde taste. For this reason the pure architectural innovations were not largely followed by other architects. Most other Art Nouveau dwellings in Belgium and other European countries were inspired by Horta's 'whiplash' decorative style which is mostly applied to a more traditional building.
The Hôtel Tassel had a decisive influence on the French Art Nouveau architect Hector Guimard who later developed a personal interpretation of Horta's example.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.
