When you enter Exeter Cathedral it is easy too see why thousands of people visit it every year. In front of you runs the longest, continuous medieval stone vault in the world, which, can only be described as awesome. Where each rib of the tierceron vaulting meets, there is a beautifully carved boss. Many of the bosses are of a bright gold colour and most of the bosses are highly coloured, illustrating that medieval churches were once dominated by vibrant colours. Gothic architecture was devised to allow in as much light as possible and this cathedral certainly meets that goal. Beautiful, gothic windows adorn the building and there are many fascinating features to search for such as misericords, green men and an early 15th century medieval clock.
