Peetri (Peeter)

Almost certainly Peter the Great, ruled 1682-1721, widely considered the greatest of male Russian monarchs, and go-to Tsar for any Russian-based naming-project not involving the Soviets, the main one being Peter the Great’s Naval Fortress, aka the Tallinn-Porkkala defence station built under Nicholas II, designed to protect Russia from attack by sea following the 1905 destruction of the Russian Baltic Fleet in the Battle of Tsushima, effectively ending the Russo-Japanese war. The distance between Tallinn and Porkkala (±36 km) was considered sufficient for guns on either side to create a barrier to any navy intent on attacking Saint Petersburg. See also Sõjakooli.
