Ringwil.

River Ringwil in the Eastern end of Wall of Andram. Ringwil was a tributary to Narog, it had its spring in the Wall of Andram and ran 20 Miles East in deep gorges before it joined Narog North of Nargothrond as it passed the caves. Ringwil was a short and foaming stream who tumbled ahead intil it met Narog. Over the river was build a slender bridge, the only way to enter Nargothrond until Turin persuaded Orodreth to build the bridge crossing Narog.
