The crypt held relics of St Andrew. There are two entrances: one, used by the monks, which is now blocked off, and a second, for the use of pilgrims, accessed by a trapdoor in the floor of the present church, which is only opened when there's an attendant on hand to warm visitors about the steps- which are treacherously steep and deep.
Here's Ruth, my sister-in-law, admiring some recycled Roman fancywork.
The present church is spectacular but, if you're a medieval nut like me, a bit of a disappointment. The 19th century restoration was so thorough that it was more like a rebuild- and there's hardly any stonework showing that isn't crisp and machine-cut . By way of compensation the building houses so many antiquities and curiosities and ancient artworks that it's virtually a museum. There are Roman altars and tombstones, sections of Saxon crosses, a set of misericords, a collection of fifteenth century paintings on wood- including several panels of the Dance of Death and- most splendid of all- a group of medieval grotesques in high relief, including these critters.
The town is very pretty. There's an old gaol we didn't visit. I recommend the Chinese takeaway in the town centre.
