York Minster

built on Roman ruins
York Minster is famous for
coloured glass windows


Outside the front entrance of the Minster is a statue of Emperor Constantine who, on 25 July 306 AD, was proclaimed Emperor of the Western Roman Empire by his troops in York (then Eboracum).
Eboracum had been an important Roman stronghold in Britain from about 70 AD. Indeed between 208 and 211, Septimus Severus had ruled the Roman Empire from York. He also died there, on 4 February 211.

The Rose Window was produced in the year 1515 by the workshop of Master Glazier Robert Petty. The outer panels contain two red Lancastrian roses, alternating with panels containing two red and white Tudor roses.
This alluded to the union of the Houses of Lancaster and York through the marriage of Henry VII and Elizabeth of York in 1486, and may have been designed to enforce the legitimacy of the new ruling house of Tudor.
There are about 128 stained glass windows in York Minster, made from more than 2 million separate glass pieces.

York Minster is famous for its 15th-century stained glass, especially its Great East Window, which is the size of a tennis court. The window's fine details, far too tiny to see from the floor, were originally intended for God's eyes only.

York is the only UK cathedral to put mistletoe on the high altar
This ancient use of mistletoe is connected to Britain’s druid past, which was particularly strong in the north of England. The mistletoe, which grows on lime, poplar, apple and hawthorn trees, was held in high regard by the Druids, who believed it warded off evil spirits and represented friendship.
