<P> Spandrels usually provide pressure along the upper edge of the conoids . In the Henry VII Chapel, these spandrels are replaced with hanging pendants . The pendants still provide the compression necessary to support the conoids and add complexity to the aesthetics of the room . </P> <P> The pendants serve an additional structural purpose . The pendants are cut from single stones and inserted as wedge stones in the transverse arches . By combining with the transverse arches, the pendants do not require additional structural support . </P> <P> At the time of the construction of the chapel, pendant vaults were very new; they were first seen in the Divinity School at Oxford . </P> <P> The chapel's architect is unknown, but it is believed that Robert Janyns the Younger was responsible for the design of much of the structure . The structure of the chapel is a three - aisled nave composed of four bays . The aisles are divided by rows of mahogany stalls into the North, South, and Central aisles . All contain numerous monuments and floor stones dedicated to various nobles . Above the stalls, at the triforium level, are many sculptures . Interspersed between the sculptures are the heraldic banners of the knights of the Order of Bath . Above this is the clerestory, with three rows of smaller windows . The window tracery articulates four larger windows, one in each bay, each composed of these three rows of smaller lancet windows . As much of the original glass was destroyed during the Restoration, the East Window, over the center apsidal chapel, as well as the Donor Windows (in the west), in the chapels themselves, are new additions, installed in 2000 and 1995, respectively . In 2013, two new stained glass windows designed by Hughie O'Donoghue were installed on either side of the East Window . </P>
