Saint Birgitta's chapel

Saint Birgitta's chapel is located on the east coast of the island of Öland, Sweden, some four kilometers from the village of Bredsättra in Bredsättra socken, Borgholm Municipality, in a marshy area called Kapelludden. The chapel dates from the 13th century; today nothing remains but the foundation and the eastern wall, the western wall having fallen down during a storm in 1914.
