The Radisson Royal Hotel is a five-star luxury hotel which still maintains its historic name of Hotel Ukraina. Hotel Ukraina was commissioned by Joseph Stalin. It was designed by Arkady Mordvinov and Vyacheslav Oltarzhevsky (leading Soviet expert on steel-framed highrise construction), and is the second tallest of the neoclassical Stalin-era 'seven sisters' (198 m, with 34 stories). It was the tallest hotel in the world from the time of its construction until the Westin Peachtree Plaza Hotel opened in Atlanta, Georgia, United States in 1976. Construction on the low river bank meant that the builders had to dig well below the water level. This was enabled by an ingenious water retention system, using a perimeter of needle pumps driven deep into the ground.
The hotel opened on May 25, 1957. It closed in 2007 for a complete renovation and restoration. In 2009, the owners signed a contract with the Rezidor Hotel Group to manage the hotel as the Radisson Royal Hotel, Moscow. The hotel maintains its original name, however, for some purposes.
The hotel reopened on April 28, 2010 after its 3-year-renovation. The façade was restored in detail, while modern technology has been added, including multi-level water cleaning systems and air circulation systems.
There are also about 1,200 original paintings by the most prominent Russian artists of the first half of the 20th century, and on the first floor the diorama Moscow – Capital of the USSR in 1:75 scale shows the historical centre of Moscow and the city’s surroundings from Luzjniki to Zemlyanoi Val in the year 1977, when the artwork was created.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
