The City of Armagh, sometimes referred to as "The Ecclesiastical Capital of Ireland", has two cathedrals, Church of Ireland (left picture) and Roman Catholic (right picture). They are both named St Patrick's Cathedral, after the patron saint of Ireland.
If you know how to look at such things, you can see the shapes of two shooting stars in the architecture of the cathedrals.
