Groov
Former Rhine island in Cologne-Zündorf, transformed between 1974 and 1978 into a leisure area with a marina, swimming facilities, and green spaces along the river.
The Groov is a former island with a silted-up river channel on the Rhine in the Cologne district of Zündorf. Between 1974 and 1978, a marina and recreational area were developed here between the Rhine and the Leinpfad, a historic towpath.

The name "Groov" derives from the Gaulish word *grave* (gravel, sandbank) and is pronounced with a long open "o" – and the site once hosted a natural harbour complete with two working cranes, which gradually silted up after Cologne's staple rights were abolished in 1831, eventually transforming the old trading post into a leisure island.

Name and History
The name Groov derives from the Gaulish word grave, meaning gravel, gravel bank, or sandbar; it is pronounced with a long, open "o". A Rhine channel separated the area from the main river early on, creating a natural harbour where two cranes once operated. After Cologne's staple rights were abolished in 1831, the harbour fell into disuse and began to silt up. In 1849 a dam connected the island upstream to the riverbank, and from 1862 onward groynes extended the area on the Rhine side. A further dam divided the old harbour into two bodies of water. The lower Rhine channel remained navigable for shallow-draught vessels until the mid-20th century before finally silting up.
Today
Shielded from the Rhine by an embankment, the grounds are criss-crossed by shaded cycling and walking paths. These are complemented by sunbathing lawns, sports and play areas, a mini-golf course, a combination swimming facility, and a rowing pond. The island's market square is lined with garden restaurants and beer gardens. A Rhine ferry runs daily throughout the summer, connecting the area to the Cologne district of Weiß. In harsh winters, the frozen surfaces of the two lakes serve as natural skating rinks.
Flood Protection and Monuments
In 2005 the island was raised by landfill to improve flood protection for the surrounding houses, and sheet pile joints were embedded in the floor of the market square. The occasion was also used to restore the Column of St. Nepomuk at the centre of the square, dedicated to the patron saint of sailors and seafarers. A further memorial commemorates by name the war dead from Zündorf.
