Saint Birgitta's chapel
Sweden
Saint Birgitta's chapel (Swedish: Sankt Britas kapell) 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.
