Kanzler-Teehaus, Garden tea house in Palais Schaumburg park, Bonn, Germany.

Kanzler-Teehaus is a garden tea house in the Palais Schaumburg park on the Rhine riverbank, featuring an underground chamber of about 25 square meters, a small kitchen, and a terrace facing the water. The structure connects functional rooms with an open view of the landscape.

Built in 1955 at Konrad Adenauer's request, the tea house stands on the foundations of a garden hall designed by Johann Georg Eberlein, part of the Villa Selve demolished that year. It served chancellors for confidential talks outside official protocol, so no guest lists were kept. After the government moved to Berlin in 1999, it lost its official function and was placed under monument protection in 2001.

The pavilion was nicknamed "Konradsruh" by Adenauer's staff and later by the public. Because meetings there were off the protocol, no guest lists were kept. Adenauer regularly invited US press correspondents there before his trips to the United States.

The tea house is not freely accessible: since April 2011 it can be seen only on guided tours organised by the Besucherdienst of the Haus der Geschichte, together with the Kanzlerbungalow. The pavilion sits at the lower end of the Palais Schaumburg park by the Wilhelm-Spiritus-Ufer, and the terrace faces the Rhine.

In June 1989, Chancellor Helmut Kohl and Soviet leader Mikhail Gorbachev held discussions here about German reunification. This meeting was a pivotal moment that would reshape the continent's political future.
