The village of Naisiai was a rather unremarkable settlement with no special natural attractions or places of interest. Things started to change at the end of 2014, when a capsule with a letter from the inhabitants of Naisiai to future generations was buried in the ground, and the construction of the 200-metre-long, 160-metre-wide Baltic Arena with 16-metre-high slopes began.
Later, the Lake of Happiness was excavated, the Naisiai Regional Museum was built, and an open-air sculpture park of the Baltic Gods was created. The landscape has been enlivened by the construction of the Forest Rings Trail, the creation of Rabbit Island, the Fire Square, the construction of a swing park, and the creation of a wide range of attractions for families with children to spend their free time in an interesting, active and enriching way.
