bank palace, which was built between 1901 and 1902 at the initiative of the tobacco trader TH. Gustafsson. The local architect Tore E: son Lindhberg made the drawings. In 1939 the facade was modernized, and subsequently restored when the building was completely renovated in 1975. The hospital on Orionkullen was built 1777-78. Until 1823, the building served as lazaretto of the Royal Order of the Seraphim. After 1823, the building became a private residence. From 1844, the buildings were used as city hall and for higher education. In 1907 the council administration moved from Orionkullen, allowing the educational institution to expand. As the school faculty moved to the new secondary school building at Erik Dahlberg's road, a girls' school moved in. The girls' school at Orionkullen closed in 1968. The building is home to a cultural centre today. The area where the secondary school moved is east of the canal, the Museum of Biology and the present day city hospital. After the 1960s upper secondary school reform, the institution became a Gymnasium Secondary school. Close to the school lies Mälarparken, which is home to the professional Miniature golf course. They local team has won several championships. The City Council offices were also located by the park before moving to the intersection of Nygatan/Torekällgatan. Södertälje's current hospital is across the street from the secondary school. It is houses one of the county's six trauma centres. It opened in 1907, but has been expanded and renovated on several occasions, most recently in 2017. As the land post-glacial rebound made Södertälje Canal shallower, it became increasingly difficult for merchants to get between Lake Mälaren and the Baltic Sea to sell their goods. It was decided to build a square in Södertälje, where they could meet to and hold markets. The location of the square was carefully selected so it would be located equidistant between the city's ports at Baltic Sea and Lake Mälaren. This way, merchants did not have to drag their goods longer than was absolutely necessary. The main square in Södertälje is thus not primarily designed as a trading place for the city's inhabitants themselves. For hundreds of years, Stortorget was very important because of the lively square trade held there. At that time, Stortorget was regarded as the city's centremost place. In modern times, when most trade is conducted in stores, the importance of the square has diminished. Marenplan has
