English Other Architecture ...a cross or a figure

Is there a general term denoting the various types of structures which crown steeples, towers etc. (usually of churches, from Gothic to Rococo, but also town hall towers), and look like combined spire+lantern+dome or cupola+orb etc. (not all of them necessarily), sometimes topped by a cross of a figure, decorated with pinnacles etc., frequently faced with copper or tiles?
