The village contains two churches in the same churchyard, one, St Mary's, and now redundant, the other the only church in England to be dedicated to Saint Adelwold.
St Adelwold (Alvingham with Yarburgh and North Cockerington) is in the Mid Marsh group of churches with Great Carlton, South Cockerington, and Grimoldby, and based in Grimoldby. The religious parish is larger than the civil parish, as it includes North Cockerington, a civil parish.
