TNC26 theme revealed!
The Finnish word sisu is untranslatable, but overall it can be explained as a concept encompassing inner strength, tenacity, determination, and courage, particularly in the face of adversity.
In a changing world, the TNC26 theme seems very fitting: our community needs to embrace the idea of sisu to ensure our future as a community. With this action-orientated mindset, we need the courage to make difficult decisions about our response to world events, to ensure a sustainable future for our activities and to maintain the strong ecosystem we have built.
Sisu is an all-purpose philosophy of life and as such it underpins all aspects of the NREN community.
Thanks for inviting us in Helsinki!

TNC26 Venue
The Helsinki Music Hall (Helsingin Musiikkitalo in Finnish), is a concert hall and a music centre. The building is home to Sibelius Music Academy and two symphony orchestras, the Finnish Radio Symphony Orchestra and the Helsinki Philharmonic Orchestra. The new Music Hall, opened in August 2011, is the first ever venue in Finland’s capital city specifically designed and intended for the performing of symphonic music.
All of Musiikkitalo’s halls provide wheelchair-accessible seating. In the Concert Hall, however, stairs must be used to reach non-accessible seats. There are accessible restrooms on all floors of Musiikkitalo.
TNC26 Side Meetings will instead take place at the Finland Hall, which is next door to the Helsinki Music Hall.
