The founder of the Red Cross and Nobel Peace Prize laureate Henry Dunant spent the last few years of his life in Heiden. A museum devoted to him has been established in the former district hospital.

The museum is currently closed for reconstruction. A new core exhibition on the initiator of the International Red Cross will be on display from 2024 on. 

As of April 1st 2023, events will take place and workshops for schools and private groups (on demand) will be available.
