Ombu

Ombú lies in the rolling country east of the lower Uruguay River. Streams from the San Salvador uplands flow west towards the great river, crossing a landscape of grassland and riverbank woodland. The ombú, a tree with a broad crown and a massive trunk, grows in the plains and along watercourses of the Río de la Plata region. Its name is preserved in the locality later called Ombúes de Lavalle.

The later city of Colonia del Sacramento lies here.
