Opernbrunnen
Mosaic fountain in front of Cologne's Opera House, incorporating tiles from Aristotle Onassis's yacht and the bombed-out Kaiser Wilhelm Memorial Church in Berlin.
since 1966
The Opernbrunnen is the centrepiece of the square in front of the Cologne Opera House. It is best known for the fragments of foreign mosaics worked into its surface — including pieces from the yacht of shipping magnate Aristotle Onassis and from the ruins of Berlin's Kaiser Wilhelm Memorial Church.

Design
The circular structure is clad in ceramic and glass mosaics, lit after dark by underwater spotlights. A central fountain jet rises to a height proportioned to the basin, while additional nozzles spray water outward in a wreath-like arc.
Incorporated Mosaics
Alongside his own mosaic work, designer Grümmer wove in fragments from other sources as a kind of artistic quotation. These include ceramic mosaics from the swimming pool of Aristotle Onassis's yacht Tina, and mosaic pieces depicting an apostle's head salvaged from Berlin's war-damaged Kaiser Wilhelm Memorial Church.
Decay and Restoration
For many years the fountain ran dry due to the city's financial constraints — colours calcified, nozzles failed, and the original lighting was dismantled after 1994. From 2011 onwards, the late artist's daughter campaigned for donations and a restoration, supported by local residents and Cologne institutions. Under the motto "Eat chocolate for heritage conservation," she sold a specially labelled Opernbrunnen charity chocolate to kick-start the project. The restoration was carried out alongside the renovation of the opera and playhouse complex: by July 2016 the mosaic work was complete, 14 new LED underwater spotlights had been installed, along with a descaling system and automatic water top-up. Final technical sign-off took place in spring 2017.
Today
The fountain serves as a popular meeting point in the city centre. In 2019, metal thieves stole the outer nozzle rings responsible for the wreath-shaped spray. Since then the fountain has operated in reduced form — only the central jet runs — as the unusual curvature of the missing rings makes replacement difficult to commission.
