River Adda (Afon Adda in Welsh) is a small watercourse which flows through the city of Bangor in North Wales before discharging into the Menai Strait at Hirael Bay, opposite Porth Penrhyn.
[1] Lôn Las Adda (a foot and cycle path) follows closely the course of the river for much of its length.
In 2016 Dr Zoe Skoulding and Ben Stammers ran a project called rAdda, which was supported by a number of statutory and other bodies.
The project sought to explore the relationship between the river and the people of Bangor.
It included an interpreted walk along the course of the Adda, and a multi-media performance in Storiel gallery, which featured photographs; spoken, and recorded words, and music.
