In 1716, the Turkish Gate was built in memory of the victory over the Turks in Helmstedt in the same year.
It served as entrance to the Domänenhof from the present Bundesstraße 1 and stood in alignment with the dovecote. It was badly damaged during an air raid and rebuilt in its present location in 1986.
The gable depicts the imperial emblem and above the side entrances the emblem of the abbot and prior of the monastery during which term the gate was constructed. The gate was the main portal to the former monastery St. Ludgeri.
The construction of the Turkish Gate as a triumphal arch expressed for abbot and prior as well as the joy of victory, also solidarity with the emperor, who was in control of the secular issues.
The relational connection to the House Braunschweig might have played an important role.
