The Cathedral building has changed over time to meet new needs and styles. Here, in the south-west nave corner, you can see the round 'rose' window has three different frames from different stages of the Cathedral’s history.
The lowest blocked frame dates to the twelfth century. In the 14th century, Bishop Gower wanted to let more light inside and had larger windows built, which can be seen in the larger curved frame. Gilbert Scott’s 19th century renovation preserved the window’s history. It is now filled with 20th-century stained glass by the William Morris Company.
