After the death of Henry VIII until 1834, the building served as the chamber of the House of Commons of England and that of Great Britain.
According to Cooke (1987), King Henry III witnessed the consecration of the Sainte Chapelle in Paris in 1248, and wished to construct a chapel in his principal palace at Westminster to rival it.
[3] The other marriage occurred on 15 January 1478, between the younger of the two Princes in the Tower, Richard, Duke of York, and Anne Mowbray.
Henry's son, King Edward VI, instituted the Abolition of Chantries Acts, 1545 and 1547, and St Stephen's Chapel thus became available for use as the debating chamber of the House of Commons.
The members sat facing one another in the medieval choir stalls, creating the adversarial seating plan that persists in the chamber of the Commons to this day.
Inside, the walls were reduced in thickness to accommodate extra seating and the addition of upper-level male-only public galleries along both sides of the chamber, and the remains of the medieval interior were concealed behind wainscoting and oak panelling.
A false ceiling was installed in the chamber to help to improve its acoustics, the quality of which was important in an age without artificial amplification.
The fire of 1834 totally destroyed the main body of the chapel, with the crypt below, and the adjoining cloisters, barely surviving.
Although it was demolished shortly after the fire, the surviving stone shell of the chapel, with all its later additions burned away, attracted many visitors and antiquaries who came to view the original medieval decorations which had become visible once again.
