Stronghold Warmth, situated in a nature reserve on the 

island of Ameland, is a geothermal heat plant that offers 

the experience of warm water directly at the source. It is a 

sanctuary for nature enthusiasts and travelers who hike 

across the mudflats. 

Until recently the site was used for mining natural gas and is

by coincidence situated above usable geothermal heat source. 

By transforming the old infrastructure it’s not only a 

functional redevelopment, but also a fruitful energy source 

adaptation.
