When the Rathsmühle in Celle is clad in scaffolding for its renovation, a public art exhibition takes shape on its façade. Selected paintings are shown as large-format printed banners on the scaffolding, clearly visible to everyone passing by. For a long time to come, a building site becomes an open-air gallery.
A landmark in transition
The Rathsmühle is one of the oldest sites in Celle. A mill on this spot on the river Aller is mentioned as early as 1378, and from 1389 it belonged to the town, which is how it came by the name Rathsmühle (the town-council mill). The present brick building dates from 1898/99, and flour was milled here until 2009. Today the mill is a listed monument.
Now a new chapter begins: as its owner, Stadtwerke Celle is having the building renovated in keeping with its listed status. The yellow render is coming off, the historic brickwork beneath is coming back into view, and a glass structure is set to crown the roof. It is precisely in this in-between period that the façade exhibition takes its place.
Art on the scaffolding
For the exhibition, Denk.Mal issued a public call for artists to submit their work. The selected works are printed as banners of around two by two metres and mounted on the scaffolding. The first banners went up on 9 October 2026, and thanks to a second scaffold the rest joined them in time for the opening on 4 November. The scaffolding will stay up longer than originally planned, for as long as the building work lasts. The project is created in cooperation with the town of Celle and belongs to the Art & Culture programme group.
At the opening, as at an earlier exhibition by the team, there was live spraying and painting on site: Daniel Wunn spray-painted a banner, and a group of pupils from Oberschule Westercelle painted a picture together.
Not the first time
Back in 2020, the same team already turned a Celle façade into an exhibition. The Rathsmühle carries this idea forward at one of the most visible spots in the town, now under its own association Denk.Mal e.V.

For the opening, Doris Hennies talked to Zandra Gröschner and Roman Thomas about the idea, the selection from more than 340 works and hanging the banners on the scaffolding.
