St Andrew's Church is a ruined church located above Church Ope Cove on the Isle of Portland, Dorset, England. St Andrew's was Portland's first parish church and remained as such until the mid-18th century. It is now one of the island's prime historical sites,[1][2] and is a Grade II* Listed Building and a Scheduled Monument.[3] The southern retaining wall of the churchyard is also Grade II Listed,[4] as are three remaining churchyard monuments, approximately 7 metres south of the church.[5]
