Solar Egg by Bigert & Bergström is not just an amazing sculpture but is also a sauna and it has been set up in the courtyard of Kunsthal Charlottenborg … the Royal Academy of Fine Art in the centre of Copenhagen.

You can book the sauna on Wednesdays, when it is free, or on Saturdays and Sundays and you can rent a towel, slippers and a kimono though you have to bring your own huzzpah … this is a large and popular public square. 

the Solar Egg is at Kunsthal Charlottenborg through until 13 January 2019
