Ushakovo, Novomoskovsky Rural Okrug, Guryevsky District, Kaliningrad Oblast
Ushakovo is a village in the Russian enclave Kaliningrad Oblast. It is situated at the mouth of the Prokhladnaya River at the Vistula Lagoon.
The Battle of Pokarwis between pagan Prussians and the Teutonic Knights took place nearby in 1261. The Teutonic Knights founded the village as Brandenburg to honor Otto III, Margrave of Brandenburg who supported the order in the Prussian Crusade, and erected a castle in 1266. It became known as "Brandenburg " and "Brandenburg in Ostpreußen" to differentiate it from Brandenburg an der Havel.
