Heritage Open Day: A chance to visit the historic, 13th century church at Calbourne, with a guided tour Visitors to the Grade II* listed building can enjoy a thirty minute guided tour of this interesting rural church or simply wander around and appreciate the unusual and interesting details. There will also be an art exhibition of our rural village architecture and an historical quiz trail to follow. Perched on a small hill at the top of the Village Green, a church has stood in this location for over a thousand years and is very much at the heart of the Calbourne community.
