The most interesting feature is the astonishing tomb of Sir Ralph Grey (d 1443) and his wife Elizabeth in the north transept.
The tomb is made of sandstone and alabaster and the carving is incredibly detailed in an opulent, over-the-top style.

You are left with no doubt that Sir Ralph's heirs wanted to impress and awe you with the grandeur of his memorial.
You can still see obvious traces of paint that gives a hint of how spectacular the tomb must have been when it was new. Even today, after the passage of over 5 centuries, it is stunning.

The base of the tomb chest is decorated with carved figures of 14 saints separated by heraldic shields. In the centre of each side is a pair of larger angels bearing shields.
Above the figures of Sir Ralph and Lady Elizabeth is an ornate reredos holding another heraldic shield, flanked by demi-angels.
Over the reredos is a later addition bearing the Royalist motto 'De bon vouloir servir le Roy' (which translates as 'to serve the king with goodwill').

Sir Ralph fought for the Lancastrian side in the Wars of the Roses, while his son fought for the Yorkist cause.
When the Lancastrians had the upper hand Sir Ralph sentenced his own son to death by hanging, drawing, and quartering. The sentence was eased at the last minute and the younger Grey was 'only' beheaded.
