full_context: Document 1: Warsaw: The Saxon Garden, covering the area of 15.5 ha, was formally a royal garden. There are over 100 different species of trees and the avenues are a place to sit and relax. At the east end of the park, the Tomb of the Unknown Soldier is situated. In the 19th century the Krasiński Palace Garden was remodelled by Franciszek Szanior. Within the central area of the park one can still find old trees dating from that period: maidenhair tree, black walnut, Turkish hazel and Caucasian wingnut trees. With its benches, flower carpets, a pond with ducks on and a playground for kids, the Krasiński Palace Garden is a popular strolling destination for the Varsovians. The Monument of the Warsaw Ghetto Uprising is also situated here. The Łazienki Park covers the area of 76 ha. The unique character and history of the park is reflected in its landscape architecture (pavilions, sculptures, bridges, cascades, ponds) and vegetation (domestic and foreign species of trees and bushes). What makes this park different from other green spaces in Warsaw is the presence of peacocks and pheasants, which can be seen here walking around freely, and royal carps in the pond. The Wilanów Palace Park, dates back to the second half of the 17th century. It covers the area of 43 ha. Its central French-styled area corresponds to the ancient, baroque forms of the palace. The eastern section of the park, closest to the Palace, is the two-level garden with a terrace facing the pond. The park around the Królikarnia Palace is situated on the old escarpment of the Vistula. The park has lanes running on a few levels deep into the ravines on both sides of the palace.
