the centrally located neighbourhood of Mariekälla, which is named after one of the city's water springs. On Parkgatan, which is a parallel street to the district's main street Mariekällgatan, lies Villa Walhall. The villa was built in 1875 by engineer Ludvig Jerving. Villa Walhall and Villa Bellevue were considered so typical of the resort town Södertälje that they were described and depicted in a series of articles in the magazine in 1881. Most restaurants and bars are located around Lake Maren. Marenplan square (formerly called Stadshamnen port), served as Södertälje's most important port until the construction of Mälarhamnen port in 1880. When Marenplan served as city port, ships carrying goods would moor there, and sell their merchandise to individuals and traders waiting at the quay. Boat traffic to inner Maren continued until 1963, when the Maren Bridge between Strandgatan and Lotsudden was built. The bridge was only intended as a temporary solution, and became demolished in 1993. The Maren Bridge subsequently replaced a pedestrian and bicycle bridge. The initial plan was to have the bridge removed during the summer months to allow boats to moor in inner Maren seasonally. The bridge subsequently became year-round fixed link. The Sorbonne house lies where Lotsudden and Marenplan meet. It was built in 1905, and served as studio for photographer David Sorbon until 1928. The building was completely renovated in 1985-86, to accommodate several residential apartments and a restaurant. Just above Marenplan lies the square Olof Palmes plats, which was named after the murdered Prime Minister Olof Palme. Among the buildings on the square is the old bank palace that used to belong to Södertälje Sparbank. Like many other buildings in Södertälje, the city's patron saint Ragnhild of Tälje (Swedish: ) is depicted on the facade. The importance of Olof Palmes plats was especially high when it served as hub for the city buses, which have since been moved to the Central Railway Station. The streets Storgatan, Badhusgatan and Järnagatan begin at Olof Palmes plats. Most department stores and high street shopping are located on (English: the Pedestrian street), which is the pedestrian part of Storgatan that runs between Torekällgatan and Stortorget. The pedestrian street is dominated by modern department stores, built during the 1960s. The largest are (architect Erik and Tore Ahlsén), , and (which initially was a Domus department store). A notable exception to the otherwise modern structures is Skandinaviska Enskilda Bankens
