The Chesil Rectory is a very nice restaurant in Winchester. It's a Grade II listed building dating back to 1450, and still retains many original features including solid oak beams, ancient doorways and beautiful open fireplaces. On their website they say they are "the oldest house in Winchester" but we already know that The Old Blue Boar also claims to be the oldest! Whatever! They are both very old!
The word Chesil is believed to be a derivative of the old English "chisol", meaning a shingly beach or bank.
