This gothic-style Roman Rite Catholic cathedral was built between 1194-1250 and is the last cathedral to have occupied the grounds since the 4th century. The church’s almost perfect preservation is astounding; it still holds most of the original stained glass windows and its architecture has gone almost unscathed since the 13th century. Dominating the cathedrals exterior are its flying buttresses, large windows, and beautiful spires. Loire Valley
