Soon after Putin returned from his KGB service in Dresden, East Germany, he built a dacha in Solovyovka on the eastern shore of Lake Komsomolskoye on the Karelian Isthmus in Priozersky District of Leningrad Oblast, near St. Petersburg. After the dacha burned down in 1996, Putin built a new one identical to the original and was joined by a group of seven friends who built dachas nearby. In 1996, the group formally registered their fraternity as a co-operative society, calling it Ozero ("Lake") and turning it into a gated community.
