The building of the former Prussian government for the administrative district of Koblenz and the main tax office was built from 1902 to 1906 under the direction of the Berlin secret building officer Paul Kieschke and the Koblenz building authority on the site of the former Electoral Trier orphanage in the Wilhelminian neo-romantic style. Emperor Wilhelm II personally made changes to the plan regarding the towers and roofs. His concern was to build on the Staufer period, which was regarded as a model of national greatness.
The 158 m long neo-Romanesque building, which once housed the (district) government of the Koblenz district, the main tax office, still decisively defines the image of the Rhine front today. A mighty neo-Romanesque complex arose around two inner courtyards with side wings. The four-storey main front on the bank with a massive gabled central pavilion looks like a fort due to the large corner towers and the tufa cladding of the facades. Inside are monumental stairways with vaulted halls and outstanding stone carvings.
The Presidium of the Federal Office for Defense Technology and Procurement has been located in the former Prussian government building since 1961, and after the restoration work was completed in 1993, the Koblenz Higher Regional Court was located in the southern part.
