It was a typical early Norman design with solid pillars and arches.[24] In 1074 D'Oyly and his close friend, Roger d'Ivry had endowed a chapel with a college of priests, which is presumed to be the structure in question; at an early stage it acquired a dedication to Saint George. As detailed below, the crypt of this chapel still survives, albeit in a new location within the castle, having been moved and reconstructed from its original materials in 1794.
