The newly created attic space above the ceiling housed a ventilation lantern and was used as the ladies' gallery, although the view down into the chamber beneath through the lantern was severely restricted. More seating was later added for the extra members brought in by the Acts of Union with Scotland (1707) and Ireland (1800). By the 19th century, the chapel's interior had a very bland and modest look in contrast to its former medieval magnificence.
