Calcot Manor is a historic building in Calcot, three and a half miles west of Tetbury on A 4135 in Gloucestershire, England, near the junction of roads A46 and A4135. The original building was established in approximately 1300 AD by Henry of Kingswood as a tithe barn annex of Kingswood Abbey. The estate was expanded to include a 16th-century manor house and other buildings. Structures added from the Late Middle Ages to the mid-17th century include a chapel, granary, stables and other buildings. The buildings are all constructed from limestone; which are locally quarried stones that are typically flat and easily stacked for drystone wall purposes.
