The baumall was part of the Hamburg city fortifications built between 1616 and 1625 . He separated the water to at the Alster nearby estuary inland port from the northern Elbe . Today a street of the same name across it reminds of it.
Until 1852, the inland port was made impassable with tree trunks at night, hence the name. The port area beyond this safe zone was called Niederhafen . Today there is a sport boat harbor in the Niederhafen .
The two port police guards who were responsible for this security had to give way to the construction of the Hamburg subway in 1911 . A stop of the same name was also built there. The elevated railway stop, which is served by the U3 today, has a steel hall. At the end of the 1980s, a second exit was set up at the western end, from which a bridge leads to the Gruner + Jahr publishing house and on to the St. Michaelis Church (Michel).
Further barriers were the Niederbaum above the Niederhafen and the Oberbaum at the Oberhafen outside the fortification . These secured the wall frame , a canal between the old town and the island of Grasbrook .
