## About

Olecko is a town in Warmian-Masurian Voivodeship beside Lake Oleckie Wielkie. Its broad market square recalls the town’s planned development in former East Prussia.

## Notes

The 1928 change from Marggrabowa to Treuburg is distinct from adoption of the postwar Polish name. Input label is Ukrainian or indirect; local\_name gives the native spelling.
