The oldest document in which Seehausen was mentioned was written in 1174.[4] Seehausen developed on riverAland in the middle of the 12th century, but the first settlement called "Altstadt" was left in the middle of the 14th century and a new town was laid out in the north.[5] Many immigrants from the Netherlands settled down in the area after 1251. In the Middle Ages Seehausen developed into a wealthy trade centre which was surrounded by a moat and a wall. It became a member of theHanseatic League in 1359.[6] As river Aland was navigable goods produced in Seeland and the area around like wheat, linnen and wool could easily be transported to the other hanseatic towns and cities. A small harbour on river Elbe just five kms from Seehausen was built in 1409.
The centre of Seehausen is St.Petri Church which was built 1170–1180 in aromanesque style and transformed into agothic hall church between 1440 - 1480.[7] The height of its impressive towers amounts to 62 metres. Itsbaroque pulpit dates from 1710, and the wood carvings of the altar, awinged altarpiece were made in the Netherlands in the 15th century[8] The organ which dates from 1867 was renovated in 2014.
The Town Hall was built of bricks inneogothic style and inaugurated in 1883.[9]
A part of the medieval town wall with a height of up to 4 metres dating from the 15th century is left and can be visited in Petristraße. The ancient rampart and moat is well-preserved, e.g. close to the former gate "Beustertor" at Hoher Wall Street. Beustertor (15th century) gate is the only one of five gates which was not demolished in the 19th century. It was the most important gate because the road to the harbour on river Elbe started from here.
Seehausen has many well-preserved half-timbered houses, especially in Beusterstraße, Steinstraße and Petristraße (built around 1750).[10] The church of a former monastery which had been dissolved in 1547 was transformed into a salt depot and named "Salzkirche (Salt Church)". It was built around 1460 in a brick gothic style typical for hanseatic towns.[11] After a renovation in 1997 it was transformed into a hall for concerts and other cultural events. - TheTurmuhrenmuseum is an exhibition of church-clocks and historical clocks. Opposite the railway station a wall painting in the socialist style of the former GDR can be seen.
There are various sights in the villages which were incorporated into Seehausen in 2010, e.g. St.Nikolaus Church (built from 1150 to 1184) in Beuster.[12] In Beuster theBlaulichtmuseum is worth a visit as well. It is a collection of army, police and ambulance vehicles. Two megalith graves from Stone Age which are about 5,000 years old can be visited near Bretsch.[13]
Seehausen has a railway station on theMagdeburg-Wittenberge railway which was built from 1846 to 1849. There are good rail connections to Berlin and Hamburg viaWittenberge, Seehausen's neighbouring town in the North.The town will be connected toMagdeburg and to the harbour ofWismar by two exits ofmotorway 14 which is under construction. The inauguration is planned for 2025. Agriculture and food processing have always played an important part in the Altmark. The metal-working industry is a most important economic factor of Seehausen and tourism is gaining importance as well. Tourism in Altmark is benefiting from the trend towards nature and activeholidays.
Hiking, cycling and horse-riding are common in Seehausen and its surroundings.Schillerhain, a large park in the South of Seehausen was laid out as early as 1852. It was inaugurated as a public park and named after the playwrightFriedrich Schiller in 1859.Waldbad, a public outdoor swimming pool in the park, founded in 1938 and renovated several times, is visited by many locals and tourists.
