City of Lappeenranta 
(population 70,000) is the economic and cultural center of southeast Finland situated near the border of Russia
and at the southern edge of the Saimaa
, the largest lake (system) of Finland
. The harbour, the parks nearby, the fortress and Myllysaari beach are a perfect place to chill out in summertime, sitting on the terraces, drinking, eating and watching the boats and things that happen. Live music played on many summer days.
Early in August there is a popular festival called "Linnoituksen yö" (Engl. The Night of the Fortress) in the harbour and fortress area.
