 The chapel was dedicated on 28 May 1621 , and extended in 1636 . The architectural historian Giles Worsley has described the chapel 's east window ( added in 1636 ) as an instance of Gothic Revival architecture , rather than Gothic Survival , since a choice was made to use an outdated style – classical architecture had become accepted as " the only style in which it was respectable to build " . Jonathan Edwards ( principal from 1686 to 1712 ) is reported to have spent £ 1 @,@ 000 ( approximately £ 134 @,@ 900 in present day terms ) during his lifetime on the interior of the chapel , including the addition of a screen separating the main part of the chapel from the ante @-@ chapel ( at the west end ) in 1693 . In 1853 , stained glass by George Hedgeland was added to the east window . In 1863 , the architect George Edmund Street was appointed to renovate the chapel . The arch of the chancel was widened , the original Jacobean woodwork was removed ( save for the screen donated by Edwards and the pulpit ) , new seats were installed , new paving was placed in the main part of the chapel and a stone reredos was added behind the altar . Views of the changes have differed . On 21 October 1864 , Building News reported that the restoration was nearing completion and was of " a very spirited character " . It said that the new " handsome " arch showed the east window " to great advantage " , with " other improvements " including a " handsome reredos " . Ernest Hardy , principal from 1921 to 1925 , said that the work was " ill @-@ considered " , described the reredos as " somewhat tawdry " and said that the Jacobean woodwork had been sold off too cheaply . In contrast , the architectural historian Nikolaus Pevsner called the reredos " heavily gorgeous " .
