Conical roof
A conical roof is a roof shape , which a right circular cone corresponding to from an acute to an obtuse angle. They were mainly used as the tower roofs of medieval city fortifications and castles . There they can either end with the outer wall of the tower (or protrude over it with a roof overhang) or stand as a helmet on the defense platform. Here, gargoyles were necessary to drain the rainwater ( Andernach , Alter Krahnen). In this case, the conical roof was surrounded by a wall, a parapet or a battlement . Conical roofs were usually made of a wooden beam construction covered with slate , in rare cases made of stone.
There are also conical roofs on church towers , e.g. B. on the towers of the Romanesque collegiate church Sankt Cyriakus in Gernrode (district of Quedlinburg, here with sheet copper roofing), the towers of St. Pantaleon in Cologne, the side towers of the Trier Cathedral and the west towers of the collegiate church St. Bonifatius in Freckenhorst.
