The 40-year-old, site-specific work of art has meant that driftwood and tree branches were built without a permit at the Kullaberg nature reserve in Skåne and has, against all odds, survived the forces of the weather, the county administrative board's demolition threat and various fires.
The work was previously sold to the artist duo Christo and Jeanne-Claude, who are both now dead.
Discussions are now underway about what will now happen to the work and who will be responsible for it.
The Christian Democrat members of parliament Magnus Jacobsson and Michael Anefur have motioned to the Riksdag that Nimis should be marked as a cultural monument and Kulturnyheter's art critic Dennis Dahlqvist believes the state should take over responsibility for the artwork.
But the Swedish Arts Council believes that they cannot buy works of art because they only buy art from now living artists.
- We can influence through opinion formation for example, but not through art purchases or cultural monuments in this situation, says Lena From art project manager Statens konstråd.
"It is a response building within a nature reserve"
Kullabergs nature reserve is owned by the County Administrative Board, which represents the state, and according to Lena From, the county administrative board could possibly take responsibility for the artwork.
Daniel Åberg, site manager for the nature reserve, says that he does not answer if it is possible.
- It is a black building within a reserve that is protected, not only as a nature reserve but also as a natura 2000 for outdoor areas with very sensitive nature, he says.
Last year, Lars Vilks and the county administrative board discussed making the long-lived black building legal, without coming to any conclusions.
Now it is unclear what will happen to the work.
Is there a risk of it being torn down?
- I do not think so, says Daniel Åberg.
