Thank you, Mitch! I was wondering about that earlier, dissecting the name and wondering how the village earned that moniker.
As with most ancient english towns, the name has evolved many times over the 2000 or so years since it was first settled.
From wiki: “The name Bicester, which has been in use since the mid 17th century, derives from earlier forms including Berncestre, Burencestre, Burcester, Biciter and Bissiter”
