"Canterbury Cathedral"

Founded in 597, the cathedral was completely rebuilt between 1070 and 1077. The east end was greatly enlarged at the beginning of the 12th century, and largely rebuilt in the Gothic style following a fire in 1174, with significant eastward extensions to accommodate the flow of pilgrims visiting the shrine of Thomas Becket, the archbishop who was murdered in the cathedral in 1170. The Norman nave and transepts survived until the late 14th century, when they were demolished to make way for the present structures. 

The architectural type is Cruciform basilica; the style is   Romanesque, Gothic.  Its five towers are 236 ft tall and it has 14 bells.

A pivotal moment in the history of the cathedral was the murder of the archbishop, Thomas Becket, in the north-west transept (also known as the Martyrdom) on Tuesday 29 December 1170, by knights of King Henry II. The king had frequent conflicts with the strong-willed Becket and is said to have exclaimed in frustration, "Will no one rid me of this turbulent priest?" Four knights took it literally and murdered Becket in his own cathedral. After the Anglo-Saxon Ælfheah in 1012, Becket was the second Archbishop of Canterbury to be murdered.

The posthumous veneration of Becket transformed the cathedral into a place of pilgrimage, necessitating both expansion of the building and an increase in wealth, via revenues from pilgrims, in order to make expansion possible.
