Onchan is a district and the name of a parish which historically included parts of the capital, Douglas. Onchan has a thriving shopping centre and a large pleasure park, as well as glens and nature walks.
The name Onchan was derived from Kirk Coonachan, a church named after a Celtic Saint. Lieutenant Buckle Reeves is buried in the churchyard of Onchan's Parish Church (St Peter's) and was the last surviving officer to have sailed with Nelson on the Victory. Captain Bligh of the Bounty married a local girl in an earlier church on the same site.
