Construction: The end of the Great Northern War resulted in the Treaty of Nystad in 1721, ceding much of the Swedish Empire's claim to the Baltic Sea to the rising Tsardom of Russia. Peter the Great already began construction of his new capital St Petersburg in 1703 after successfully capturing Swedish provinces on the eastern coast. This strategic location allowed Russian access to the Baltic Sea through the Neva River that flowed to the Gulf of Finland. The island of Kotlin and its fortress Kronstadt west of St Petersburg provided a gateway and commercial harbor access owing to the shallowness of water closer to the city.
Throughout the early 18th century, Peter the Great built and expanded the Peterhof Palace complex as a part of his goal to modernize and westernize Russia.
Layout:The dominant natural feature of Peterhof is a 16-m-high bluff lying less than 100 m from the shore. The so-called Lower Gardens (Nizhny Sad), at 1.02 km2 comprising the better part of Peterhof's land area, are confined between this bluff and the shore, stretching east and west for roughly 200 m. The majority of Peterhof's fountains are contained here, as are several small palaces and outbuildings. East of the Lower Gardens lies the Alexandria Park with 19th-century Gothic Revival structures such as the Kapella.
Atop the bluff, near the middle of the Lower Gardens, stands the Grand Palace (Bolshoi Dvorets). Behind (south) of it are the comparatively small Upper Gardens (Verhnyy Sad). Upon the bluff's face below the palace is the Grand Cascade (Bolshoi Kaskad). This and the Grand Palace are the centrepiece of the entire complex. At its foot begins the Sea Channel (Morskoi Kanal), one of the most extensive waterworks of the Baroque period, which bisects the Lower Gardens.
