Yes! There are totally wells! They're in the Bishop's Palace, and it's all very pretty and of course they're terribly ancient. Hmmn, I was going to say there were seven, but Wiki tells me:
The name Wells comes from three wells dedicated to Saint Andrew, one in the market place and two within the grounds of the Bishop's Palace and cathedral. A small Roman settlement surrounded them, which grew in importance and size under the Anglo-Saxons when King Ine of Wessex founded a minster church there in 704.
I didn't know there was one in the market place too, although the place is riddled with those square drains that look far too easy to break an ankle (or a car wheel) in, so it makes sense that there's a well where all the water comes from... Wonder where I got seven wells from...? *g* (Okay, I googled again - apparently "seven wells" is a thing, a kind of superstition-y thing, and there are actually 'seven wells' names in the Somerset limestone area, so I must have picked it up somewhere along the way! Love brains... *g*
