Peartree Green is an open space on high ground on the east bank of the River Itchen in Southampton. A 16/17th century building, Peartree House, still stands, though is today concealed by private housing. The house and the green take their name from a pear tree that grew near the parish church. Some of the original open space has been built on, but a large proportion remains as a recreational area. It contains a church and the remains of a boarding school. It overlooks the River Itchen to St Mary's Church in Southampton.
