to as just or simply ) with the city museum Södertälje Stadsmuseum, is one of the most popular sights to visit in the city. The museum first opened in 1929 when the landmark windmill and a few other buildings were moved to the site. In connection with the redevelopment of the city centre in 1961, many old buildings were moved to Torekällberget. The museum is divided into the environments "Staden" (English: the City) and "Landet" (English: the Countryside). The urban environment is built around the main square Tenngjutartorget, where markets often are held. The square is surrounded by buildings from the 1700–1800s. Several species of domestic animals are kept at the museum. The environment conveys a picture of life in rural farms around Södertälje in the 1800s and earlier. There is also a stage where ballroom dancing and performances are often arranged during the summer months. The vehicle museum Marcus Wallenberg-hallen (English: The Marcus Wallenberg Hall) is situated by Saltskogsfjärden, next to the headquarters of Scania AB. The museum is named after the industrialist Marcus Wallenberg Jr. The collections include a number of older vehicles and environments; like the first mass produced car in Sweden from 1903. It also features railway cars that were owned by the Swedish State Railways, used between the late 1800s until the early 1900s. Exhibited objects have been restored to their original condition. A little less than half of the museum consists of newer vehicles manufactured during the 2000s. Södertälje is home to a large science museum based on the book La Science Amusante by French writer Arthur Good. The museum is called Tom Tits Experiment after the author's pen name Tom Tit. It started as a temporary exhibition at Södertälje Hall of Arts (Swedish: Södertälje Konsthall), but became so popular that it was turned in to a permanent museum. The museum is located in an old industrial building at Storgatan street. Today, it is the largest Science centre in Sweden. It occupies four floors, and has a park that is open during the summer season. The exhibitions contain more than 400 science experiments. Tom Tits Experiment received around 190,000 visitors in 2018. (English: Saltskog manor) was the home of the industrialist and mecenate Carl Fredrik Liljevalch. Today it serves as a museum. The farm dates back to the 16th century. Liljevalch acquired it in 1881. Previously, the farm had been owned by the families
