Save and Preserve Project

WSP’s Save and Preserve Project came up with an ingenious—and highly sustainable—way of keeping worshippers warm in cold medieval churches on the Island of Gotland, in Sweden.

Garda Church, Gotland, Sweden

The churches are like a big cold store. In the 1970s, you could heat them but today the energy costs are too high. We were looking for solutions that use less energy so that we would still be able to use the churches and at the same time preserve the wooden carvings and paintings inside.
