Visit to the Hermitage Museum. The magnificent Hermitage Museum is the most important sight in St. Petersburg, occupying the Winter Palace, former residence of the Russian tsars, and three more adjacent buildings overlooking the Neva River. The Hermitage is Russia’s biggest museum and one of the most important in the world. It was founded in 1764 by Catherine the Great and it grew richer through the centuries as tsars purchased entire art collections abroad. Today it is home to more than three million masterpieces and hosts invaluable collections of sculptures, pictorial art, crystals, porcelain, carpets, jewellery, engravings, antiques from the classical era, modern art, weapons, medals, coins, precious books, and many more. It is well known all over the world for its collections of Italian, Flemish, French, and Spanish pictorial art, and particularly for its paintings of Leonardo da Vinci, Raphael, and Rembrandt; impressionists such as Gauguin, Matisse, and Van Gogh; and such geniuses of modern art as Picasso. Its sumptuous interiors, richly decorated by the most talented artists, are a marvellous frame for this unique collection.
