Medevi Brunn is Scandinavia's oldest spa, located in Motala Municipality on the eastern shore of Lake Vättern, in north-west Östergötland, Sweden.
The spa was founded in 1678 by Count Gustaf Soop and the royal doctor Urban Hjärne.
Queen Hedvig Eleonora had a summer residence built at Medevi säteri, on the hills overlooking the village, at the recommendation of Hjärne.
Since then, people have been coming to Medevi every summer to cure themselves from ailments by drinking the mineral water and by covering themselves in mud wraps.
The area surrounding Medevi has seen a dramatic increase in the construction of summer residences, some of which have been turned into year-round housing.
