Fallersleben Castle (German: Schloss Fallersleben) is located in Wolfsburg in the German state of Lower Saxony and, together with Neuhaus and Wolfsburg Castles, is one of the most important historic buildings in the town.
It is in the district of Fallersleben and forms an historic setting along with the castle lake, St. Michael's Church and the Old Brewery.
Numerous outbuildings belonged to the castle, such as the Old Brewery, and extensive estates that were later converted into a ducal domain (Domäne).
In the mid-17th century the ducal residence was given up and the main building of the castle became the seat of an Amt in which, from 1855, civic authorities were accommodated (finance office, court, town hall).
On the upper floor is an art gallery with paintings by Franz Hoffmann-Fallersleben (only child of Hoffmann von Fallersleben).
These exposed cellars with barrel ceilings (Tonnengewölbe) and walls 1.3 metres thick.
