The palace-and-park ensemble of Tsarskoe Selo is a superb monument of world-ranking architecture and garden-and-park design dating from the eighteenth to early twentieth centuries. A whole constellation of outstanding architects, sculptors and painters made the ideas of their crowned clients a reality here. Tsarskoe Selo is a cluster of very fine examples of Baroque and Classical architecture and it was also the first place in the Russian capital where interiors decorated in the Moderne (Art Nouveau) style appeared. More than a hundred historical monuments are scattered across the Catherine and Alexander Parks that have a joint area of 300 hectares.
