A little bit of natural beauty growing at the base of St. Margaret's Chapel, a tiny Norman building which has been standing there intact for more than 900 years. It has survived all the sieges and bombardments to which the fortress on the rock was subjected during that period. On several occasions the castle was razed - but the demolishers invariably spared the chapel of the good St Margaret because of its religious significance. Today, members of the castle garrison still have the right to be married within the Chapel.
