The walls were covered in rich fabrics that concealed machinery that controlled the two portcullises. Often, two portcullises to the main entrance would be used. It would be backed by one or more portcullises and gates. Halfway along the passage three granite portcullises guard the chambers. The grooves for the portcullises are still visible today. The connecting passage referenced above enters the passage between the two portcullises. A double gateway with two portcullises was constructed at this time. The passage would originally have had three wooden portcullises. Midway along the horizontal passage is the main barrier of three pink granite portcullises. Here too the portcullises were left open. The gatehouse included portcullises, murder-holes and a drawbridge. Additional portcullises defended the outer gate along with a drawbridge and rock-cut ditch. The arms are blazoned "Argent three Towers triple-towered Sable Portcullises Gules". In 1329, portcullises were installed at all the gates of the castle.
