 On the opposite side of the chapel is a range of buildings including the lodgings of the Military Knights , and the residence of the Governor of the Military Knights . These buildings originate from the 16th century and are still used by the Knights , who represent the Order of the Garter each Sunday . On the south side of the Ward is King Henry VIII 's gateway , which bears the coat of arms of Catherine of Aragon and forms the secondary entrance to the castle .
