Store Heddinge Church also known as Saint Katharina Church (Danish: Store Heddinge Kirke or Sankt Katharina Kirke) is an octagonal church in the town of Store Heddinge on the Danish island of Zealand. Thought to have been built of limestone in the late 12th century by King Valdemar I, the unusual octagonal Romanesque nave and the choir were later extended with lateral Gothic additions, including the tower.[1] [2]
