About us

Hanwell Community Observatory comprises a group of volunteers based in Hanwell (near Banbury, North Oxfordshire) promoting astronomy in the community. Whether you have private or educational interests in the subject, our aim is to make astronomy accessible to you. We welcome public and school groups to star parties and other events that will open up the Heavens and share with you the wonders of the cosmos. If you are a student or teacher at a local school or university, please see the Education section for details of our current activities and how you can get involved. more...

History at Hanwell

Archaeologist Stephen Wass embarked on a five year project to uncover the lost gardens of Hanwell Castle in January 2013. There have been substantial diggings all over the grounds and significant artefacts have been found.  Emerging is a picture of a very carfeully constructed and elaborate layout of walled walks and terraces. The gardens were visited in the seventeenth century by King James I and Charles I. The scientific interests of Sir Anthony Cope (d.1675) provide an interesting historic link for HCO. There is a sense of continuing in the spirit of a man, described by the Oxford Chemist, Sir Robert Plot,  as a 'great virtuoso', for his boring of cannons, polishing of stones and grinding of corn in these grounds which Plot called 'A New Atlantis'.
