Doles Sala is a peninsula in the Daugava River, near the borders of Riga.

There is a theory that German knights settled in Doles Sala even before the city of Riga was founded, but this is unproven.

Doles Sala was previously an island, and also larger, until construction of Riga HES flooded it.

Some sources list it as the second largest island in Latvia,[1] with an area of 1044 ha.

[3] There are rare dolomite outcrops in Doles Sala, which were made by the now not existing river Lebjava.
