The long southwestern promontory of Númenor that lay to the south of the Bay of Eldanna. Its inland regions were most famous for their wine-making, but as it stretched out towards the sea, its southwestern uplands became mountainous, and ended in high sea-cliffs. Where the Southwestlands met the Southeastlands, the Siril - the greatest river in Númenor - ran between the two lands, and where it flowed into the sea stood the fishing port of Nindamos, the most important settlement in this part of Númenor.
