Ypres - The Church of St. Martin destroyed by the Germans, 1914-1915 St Martin's Cathedral [Church] (Sint-Maartenskathedraal / Sint-Maartenskerk), is a church and former cathedral in the Belgian city of Ypres. It was a cathedral and the seat of the former diocese of Ypres from 1561 to 1801, and is still commonly referred to as such. At 102 metres tall, it is among the tallest buildings in Belgium. It was heavily damaged during the First World War. Subsequently (1922–1930) the ruin was cleared and the church was entirely rebuilt following the original plans, although the tower was built with a higher spire than the original.
