The thing about Georgian architecture is it's symetry. The anomaly would be decorative if it were repeated on the opposite side of the building. But it exists in isolation, thus destroying the symetry of the elevation of which it is a part.

As to the eventual disposition of the remains of King Oswald the account I have read is wildly contradictory. He was either hacked to death and dismembered the parts being placed on stakes around the battlefield, or he was impaled on a tree, or he was nailed to a tree. Hence the name Oswestry, meaning 'Oswald's Tree'.
The body parts were recovered a year after the battle by his brother Oswy and transferred to Bamborough. The head was first buried at Lindisfarne and then went to Durham and was interred with the body of St.Cuthbert. In AD 696 the bones were transferred to Bardney in Lincolnshire, but the hand and arm blessed by St. Aidan were kept, uncorrupted, at Bamborough. Other body parts were recovered and buried at St Oswald's Priory in Gloucester. An Arm was at one time a treasured relic in Peterborough Cathedral.

Confusing huh?
