The Master's residence is not particularly striking when seen from the courtyard, in part because of its initial modest form . Only the line of seven column-separated first floor windows next to the plain apsidal chapel hint at its importance. However, the river approach tells a totally different story with its highly elaborate frontages contrasting with the more dominating military facades of the Upper Castle . This palace wing is clearly a later extension, standing five storeys high, and warrants detailed examination.
