Geography

Poznań covers an area of 261.3 km2 (100.9 sq mi), and has coordinates in the range 52°17'34''–52°30'27''N, 16°44'08''–17°04'28''E. Its highest point, with an altitude of 157 m (515 ft), is the summit of Góra Moraska (Morasko Hill) within the Morasko meteorite nature reserve in the north of the city. The lowest altitude is 60 m (197 ft), in the Warta valley.

Poznań's main river is the Warta, which flows through the city from south to north. As it approaches the city centre it divides into two branches, flowing west and east of Ostrów Tumski (the cathedral island) and meeting again further north. The smaller Cybina river flows through eastern Poznań to meet the east branch of the Warta (that branch is also called Cybina – its northern section was originally a continuation of that river, while its southern section has been artificially widened to form a main stream of the Warta). Other tributaries of the Warta within Poznań are the Junikowo Stream (Strumień Junikowski), which flows through southern Poznań from the west, meeting the Warta just outside the city boundary in Luboń; the Bogdanka and Wierzbak, formerly two separate tributaries flowing from the north-west and along the north side of the city centre, now with their lower sections diverted underground; the Główna, flowing through the neighbourhood of the same name in north-east Poznań; and the Rose Stream (Strumień Różany) flowing east from Morasko in the north of the city. The course of the Warta in central Poznań was formerly quite different than today: the main stream ran between Grobla and Chwaliszewo, which were originally both islands. The branch west of Grobla (the Zgniła Warta – "rotten Warta") was filled in late in the 19th century, and the former main stream west of Chwaliszewo was diverted and filled in during the 1960s. This was done partly to prevent floods, which did serious damage to Poznań frequently throughout history.

Poznań's largest lake is Jezioro Kierskie (Kiekrz Lake) in the extreme north-west of the city (within the city boundaries since 1987). Other large lakes include Malta (an artificial lake on the lower Cybina, formed in 1952), Jezioro Strzeszyńskie (Strzeszyn Lake) on the Bogdanka, and Rusałka, an artificial lake further down the Bogdanka, formed in 1943. The latter two are popular bathing places. Kiekrz Lake is much used for sailing, while Malta is a competitive rowing and canoeing venue.

The city centre (including the Old Town, the former islands of Grobla and Chwaliszewo, the main street Święty Marcin and many other important buildings and districts) lies on the west side of the Warta. Opposite it between the two branches of the Warta is Ostrów Tumski, containing Poznań Cathedral and other ecclesiatical buildings, as well as housing and industrial facilities. Facing the cathedral on the east bank of the river is the historic district of Śródka. Large areas of apartment blocks, built from the 1960s onwards, include Rataje in the east, and Winogrady and Piątkowo north of the centre. Older residential and commercial districts include those of Wilda, Łazarz and Górczyn to the south, and Jeżyce to the west. There are also significant areas of forest within the city boundaries, particularly in the east adjoining Swarzędz, and around the lakes in the north-west.
