Sinimäed Hills

The hills are best known as the location of the Battle of Tannenberg Line, fought in World War II on July 26–August 12, 1944.

[1] Pargimägi and Põrguaugu mägi are the two higher hills - 85 and 83 m, respectively, while Tornimägi is somewhat lower, 70 m. The ridge is about 3 km long.

The location of the hills on a 5 km wide strip between the Finnish Gulf and the woods and bogs of Alutaguse is the origin of their strategic importance.

During World War I, Pargimägi with its defensive structures was part of Saint Petersburg's preliminary defence line.

In two ferocious battles lasting for 25–31 July and 2–10 August 1944 with a break of a single day, the vastly outnumbered German army group held out under the pressure of the Estonian Operation of the Soviet Leningrad Front.
