One of the most beautiful libraries. A very wide range of offerings for everyone and it is also well received. Architecturally great and with a lot of space. The roof terrace is a special place in good weather.

Mustavuori Nature Preserve, also called Black Mountain, is a hidden gem packed with military history, including a WWI Russian fortress, trenches, tunnels, and caves. The area has great forested trails for walking, hiking and biking, making it perfect for those looking to relax and escape into nature. In winter, the trails turn into ski tracks, but during the warmer months, you can totally enjoy these delightful forested paths. The highlight is a 30-meter-long cave that really adds to the cool vibe of the place. It is a great spot to explore and unwind.
