I've walked through Chippenham a couple of times myself. I want to go back & go to The Bridge House Wetherspoon's public house & the Community Hub. The church at 20:20 is St. Andrew's Church. I have been in there a couple of times. I made the mistake of sitting by the river for a 'quiet' bite to eat of my pasty & got landed on by numerous pigeons! They were on my head, shoulders, arms & legs!
There were at 8 to 10 other people with disabilities enjoying the market place. I would think each building would have wheelchair access. I would love to just sit there at the coffee shop during a nice sunny day and people watch.
