Nindamos was a large fishing village located on the southern shores of Númenor among the marshlands at the mouth of the River Siril. Nindamos was the largest of the many small villages dotted throughout the Hyarnustar and Hyarrostar regions of the island. The region was rarely troubled by the seas or winds, and in the later centuries of Númenor the land was reclaimed and became a fertile area with many pools rich with fish.
