The Round Table at Point Alpha

The “Round Table” commemorates the discussions and dramatic events of the peaceful revolution of 1989 in the GDR. It stands directly on the former dividing line between divided Germany, as a symbol of the regained unity of the 16 federal states in peace and freedom.
The concrete parts consist of remnants of the former border fortifications.

Thanks to a generous donation from the Rasdorf family business Josef Wiegand GmbH & Co. KG, a completely new set of coats of arms of all German federal states can now be seen on the front of the round table at the Haus auf der Grenz.

A symbolic place where each stool "represents" one of the federal states and you sit together - "In unity and right and freedom for the German fatherland".
