Christ Church Cathedral
Its hilltop location and eye-catching flying buttresses make this the most photogenic of Dublin's cathedrals. It was founded in 1030 and rebuilt from 1172, mostly under the impetus of Richard de Clare, Earl of Pembroke (better known as Strongbow), the Anglo-Norman noble who invaded Ireland in 1170 and whose monument has pride of place inside.
Guided tours include the belfry, where a campanologist explains the art of bell-ringing and you can even have a go.
