I want to know the answer to the following question:
What kind of pavement was commissioned for in front of the High Altar?
All the background I'm provided with is that "Henry III also commissioned unique Cosmati pavement in front of the High Altar (the pavement has recently undergone a major cleaning and conservation programme and was re-dedicated by the Dean at a service on 21 May 2010).". Is that enough to answer the question?
