Old builduings including churches, cathedrals and temples have magnetrons and cathodes(cathedral) with the crosses on top being antennas, lots of metal including mercury, so nothing religious, and I guess that means that they were free electric power stations, reason for which every big city had one cathedral and several churches with the same architecture everywhere.
