The vast majority of Shanghai 6,340.5 km2 (2,448.1 sq mi) land area is flat, apart from a few hills in the southwest corner, with an average elevation of 4 m (13 ft) as you can see in Shanghai elevation map. The city location on the flat alluvial plain has meant that new skyscrapers must be built with deep concrete piles to stop them from sinking into the soft ground. The highest elevation point of Shanghai is at the peak of Dajinshan Island at 103 m (338 ft).
Dajinshan Island (Big Jinshan Island), Xiaojinshan Island (Small Jinshan Island), and Fushan Island in Jinshan District are nature reserves under city jurisdiction. Dajinshan has the highest elevation point in Shanghai with an altitude of 103.4 m as its shown in Shanghai elevation map. Some alluvial islands are relatively young and the number varies over time.
