The term 'Cathedral City England' refers to four cities in England that are home to cathedrals: Ely (3 letters), Exeter (6 letters), York (4 letters), and Siena (5 letters). Each of these cities has a long history, with Ely being the site of a monastery founded in 673, Exeter having been a major Roman settlement, York being the site of a Viking invasion in 866, and Rouen having been an important trading center since the Middle Ages. All four cities have impressive cathedrals, each of which is a testament to the city's rich history.
