On the 13th and 14th September 2016 the Roman Gask Project teamed up with volunteers from Quarry Bank Mill National Trust and Wilmslow Community Archaeology to look for the 19th-century astronomical observatory that is mentioned in a number of records held at Quarry Bank and is seen on the first edition Ordnance Survey map.
Using resistance and magnetometry we were able to confirm the location of the building close to the entrance to the Upper Gardens at Quarry Bank.
We are currently preparing a more detailed report on the site, so in the meantime, we decided to include a few impressions from the survey.
