Rim Bank
The Rim Bank is the riverside walk on the edge of the Isle of Gods, running in between the Brass Bridge and presumably down to the New Bridge, perhaps even further.
These riverside walks are not named on The Streets of Ankh-Morpork and are left blank. They are named in the larger-scale map appearing on the endpapers of The Discworld Companion.
Promonent locations backing onto the Rim Bank are the Dysk Theatre and the Tanty.
