Geograph - photograph every grid square

The Roman Catholic cathedral of Our Lady and St Philip Howard sits in a commanding position adjoining the grounds of Arundel Castle, from which this photo was taken. Of the nineteen R.C. cathedrals† in England (and three in Wales) this is arguably the most ornate. Built in the French Gothic style by the architect Joseph Hansom it was dedicated (as a parish church) in 1871 just three years after it had been commissioned by the then Duke of Norfolk, Henry Fitzalan-Howard, 15th Duke.
It was raised to cathedral status, which its grandeur well deserves, in 1965 with the creation of the Diocese of Arundel and Brighton.
The second part of its dedication - to St Philip Howard - is quite interesting and unusual. Originally this was to St Philip Neri, a C16th Italian priest known as "the Apostle of Rome", but in 1971 the dedication was changed to a recently canonized ancestor of the Dukes of Norfolk, St Philip Howard. (see shared description below & TQ0107 : Tomb of St Philip Howard )

† Note: Of course all our great Gothic cathedrals were originally Roman Catholic cathedrals, becoming CofE with Henry VIII's break from Rome and the subsequent Protestant Reformation.
