Named after the Welse, a river in Brandenburg.
The Welse is a 66-kilometre tributary of the Oder that flows through the Barnim and the Uckermark and flows into the Hohensaaten-Friedrichsthal waterway at Schwedt. The street was named in 1986; in this part of Neu-Hohenschönhausen the streets are named after waters and places of the Uckermark.
