Södermanland County

Södermanland's capital is Nyköping and the largest settlement is Eskilstuna. In the sparsely populated interior, Katrineholm is the largest locality. In total, Södermanland has nine municipalities and about 300,000 inhabitants. Södermanland borders the counties of Östergötland, Örebro, Västmanland, Uppsala, Stockholm and to the Baltic Sea. It holds the popular camping route called "Sörmlandsleden" which is a system of trails covering a total of approximately 100 mil (1000 km) of walking paths in Södermanland. The county has shorelines on Sweden's third and fourth largest lakes of Mälaren and Hjälmaren. There are also numerous large lakes in the Nyköpingsån river system through the west and centre of the county. The Region Sörmland is an administrative unit, covering most of the province Södermanland. The eastern parts of the Södermanland province, largely corresponding to the Södertörn area, belong to Stockholm County.

Södermanland runs between the lake Mälaren to the north and the Baltic Sea to its east and south. There is a large distance between the two main urban areas Eskilstuna and Nyköping of roughly 80 km, and vast forested areas in between. The centre of Södermanland is spread out between four municipality seats namely Vingåker, Katrineholm, Flen and Gnesta that separate the southern and northern areas of the county. Most parts are low-lying being part of the Mälar valley, but some higher areas can be found. The interior of Södermanland has many small rolling hills, courtesy of glacial rebound that has shaped the landscape of the area. The coastline on the Baltic Sea has many bays connected to it, with Nyköping being well-shielded from the open sea by a peninsula with plenty of inlets. Offshore there are also plenty of islets making up the Sörmlandic archipelago. The county has lake tripoints with Stockholm and Uppsala in Mälaren, with Västmanland and Örebro in Hjälmaren and a land tri-point with Örebro and Östergötland just south of Högsjö. The southwest of the county marks the southernmost points of the greater regions of Svealand and the Mälaren Valley. The climate much like other parts of southern Sweden is a mix between oceanic and moderated continental. Summers highs are most often around 23 C, with lows around 12 C inland and either near or above 14 C on the coast due to the warm July sea surface temperatures. Winter highs differ between 0 C and 1 C between inland and coastal parts with lows around -4 C on the coast to -6 C inland and in the lakeside north. It can heavily fluctuate between different years with influences from different weather systems. Most often winters are still pronounced enough for the climate to be a clear four-season climate although the open sea most often remains ice-free year round.

Södermanland County inherited its coat of arms from the province of Södermanland. When it is shown with a royal crown it represents the County Administrative Board.

The province of Södermanland was divided into three counties in the 17th century; Nyköping County, Gripsholm County and Eskilstunahus County. They were merged into present day Södermanland County in 1683.
