The whispers of history linger here at Schloss Deichmannsaue. Can you feel them?
Schloss Deichmannsaue a grand building complex in Bonn’s Rungsdorf district stands proudly. Its history stretches back centuries. Originally mentioned in 1662 as the Auerhof it was transformed. The transformation began when the influential Deichmann family acquired it in 1836. This wealthy Cologne banking family sought a prestigious residence. They desired a place to host grand events previously held in Cologne. The Mehlemer Aue estate became their choice. Imagine the elegant gatherings this manor hosted. Think of the clinking glasses and lively conversations filling these very rooms.
The description in the Bonner Wochenblatt in 1836 detailed the estate’s grandeur. It described the main house with twelve rooms a hall a salon and extensive outbuildings. The beautiful English-style gardens and surrounding farmland completed the idyllic setting.
Significant changes to the Schloss began in 1856. The completion of the Cologne-Bonn railway line in 1844 was pivotal. It allowed Wilhelm Ludwig Deichmann to easily travel to his country estate. The journey from Cologne to Mehlem was reduced to just an hour. This made frequent visits much more convenient.
Upon Wilhelm Ludwig’s death his son Adolf inherited the estate. Because he lived in London he passed the property to his brother Theodor. Theodor’s son Wilhelm Theodor later inherited the estate. He embarked on a major rebuilding project between 1910 and 1912. Working with local architect Peter Wald he created the Schloss’s current appearance. This construction was built on the foundations of the old manor house.
In 1941 the Schloss was sold to the Wehrmacht. Following World War II Allied forces seized it. Belgian military forces occupied the building for a time. Then beginning September 28 1949 the US High Commission moved in. High Commissioner John McCloy took up residence in May 1950. An expansion was needed. A new building featuring 700 offices was constructed between 1951 and 1952. This new building incorporated a distinctive American-style wooden frame construction.
The Schloss served as the US Embassy until 1999. The Federal Ministry for Housing Construction later renamed to Federal Ministry for Spatial Planning Building and Urban Development also occupied the grounds. Other federal agencies including parts of the Ministry for Development Aid occupied the site through the mid-1970s.
In 1991 an attack on the US Embassy occurred. Members of the Red Army Faction (RAF) fired shots from the opposite Rhine bank. Fortunately only material damage occurred. The RAF’s motive linked the attack to the ongoing US-Iraq war.
Following German reunification and the government’s move to Berlin the Schloss needed a new purpose. The US Embassy moved to Berlin. The Federal Office for Building and Spatial Planning (BBR) occupied the site. The Federal Agency for Agriculture and Food was later added. The Schloss was renovated. This renovation included a new 800 m² canteen for the 1200 employees.
Today Schloss Deichmannsaue stands as a testament to its rich history. A place where diplomacy business and history intertwine. It is a true embodiment of Bonn’s fascinating past.
