Alzey Castle, constructed in the 13th century, was the residence and headquarters of the district administration. The castle of Alzey was a favoured place of residence for the Palsgraves during the time of both Ruprechten, Ruprecht ll and Ruprecht lll. who was King Ruprecht I of Germany from 1400 - 1410.
In the 15th and 16th centuries the castle was built into a representative castle complex which was badly destroyed during the Palatine War of Succession. As a result of the romantically inspired castle restoration movement of the 19th century, the ruin was rebuilt and restored to its historical splendour at the beginning of the 20th century. Since this time it has been used as the district court house.
