Christ Church Cathedral (The Cathedral of the Most Holy Trinity) in Dublin
is the elder of the city's two mediæval cathedrals,
the other being St. Patrick's.
It has been the seat of the archbishop of Dublin (initially Roman Catholic, then Church of Ireland) since mediæval times.
It is located at the end of Dame Street.

The cathedral was built in 1038 by King Sitric Silkenbeard, the Viking King of Dublin.
The church was built on the high ground overlooking the Viking settlement of Wood Quay.
The cathedral was the location of the coronation of Lambert Simnel in 1487 as 'King Edward VI'
a boy pretender who sought unsuccessfully to depose Henry VII of England.
