Christ Church Cathedral

Top choice church in Temple Bar

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.

Once the original wooden church was replaced by the building you see today, the cathedral vied for supremacy with nearby St Patrick's Cathedral, but like its sister church it fell on hard times in the 18th and 19th centuries – the nave had been used as a market and the crypt housed taverns – and was virtually derelict by the time restoration took place. Today both Church of Ireland cathedrals are outsiders in a largely Catholic nation.

From the southeastern entrance to the churchyard, walk past ruins of the chapter house, which dates from 1230. The entrance to the cathedral is at the southwestern corner and as you enter you face the northern wall. This survived the collapse of its southern counterpart but has also suffered from subsiding foundations.

The monument to Strongbow is in the southern aisle. The armoured figure on the tomb is unlikely to be Strongbow (it's more probably the Earl of Drogheda), but his internal organs may have been buried here. A popular legend relates that the half figure beside the tomb is Strongbow's son, who was cut in two by his father when his bravery in battle was suspect.

The southern transept contains the superb baroque tomb of the 19th Earl of Kildare (died 1734). His grandson, Lord Edward Fitzgerald, was a member of the United Irishmen and died in the abortive 1798 Rising.

An entrance just by the south transept descends to the unusually large arched crypt, which dates back to the original Viking church. Curiosities in the crypt include a glass display case housing a mummified cat chasing a mummified rat (known as Tom and Jerry), which were trapped inside an organ pipe in the 1860s! From the main entrance, a bridge, part of the 1871 to 1878 restoration, leads to Dublinia.
