St John the Baptist's Church, Flookburgh: St John the Baptist's Church is in Station Road in the village of Flookburgh, on the Cartmel Peninsula in Cumbria, England.

St Mary's Cathedral Church: St Mary's Cathedral Church, also known as St Mary's Church, is the former Cathedral Church of the Anglican Diocese of Auckland.  Located in Parnell, it replaced the earlier Old St Mary's.  This wooden Gothic Revival church was designed by the prominent Christchurch architect Benjamin Mountfort and completed in 1897.  The building served as the Cathedral Church and principal Anglican church of Auckland until 1973 when the Chancel of Holy Trinity Cathedral, for which the foundation stone was laid in 1957, came into use.  In 1982, St Mary's Church was moved across Parnell Road to its present site beside the Cathedral.

St Mary and St Nicolas, Spalding: St Mary and St Nicolas is the ancient parish church of Spalding, Lincolnshire.  It is a Grade I listed building.

St Mary Magdalene Church, Holloway Road: St Mary Magdalene Church is an Anglican church on Holloway Road in north London.  It is located in St Mary Magdalene Gardens opposite Islington Central Library.  St Mary Magdalene is part of the Parish of Hope Church Islington (previously the Parish of St Mary Magdalene and St David).  In 2013 its sister church St David's on Westbourne road was reopened so St Mary Magdalene now functions as one of two worship sites of the Parish, with a single leadership and a staff team.  The early 19th century building accommodates the activities of the church congregation, including church services, a winter night shelter, 'Mini Mags' – a toddlers group, and provides spaces to other users.  Baptisms and confirmations, marriages and funerals are regularly held here.

Christ Church, St Leonards-on-Sea: Christ Church is an Anglican church in the town and seaside resort of St Leonards-on-Sea, part of the Borough of Hastings in East Sussex, England.  Opened as the town's third Anglican church in 1860 to serve a rapidly developing residential area and to accommodate poor worshippers who could not afford pew rents at the fashionable St Leonard's and St Mary Magdalene's Churches, the original building was superseded by a much larger church built next to it between 1873 and 1875.  Prolific ecclesiastical architect Sir Arthur Blomfield's simple Gothic Revival design forms a landmark on one of St Leonards-on-Sea's main roads, continues to serve a large area of the town (including the former parish of the now closed St Mary Magdalene's Church) and maintains a strong Anglo-Catholic tradition.  It has been described as Blomfield's "finest achievement in Sussex" and "one of the main centres of Anglo-Catholic worship in Southern England".  The interior fittings are the best of any church in the borough, and the design has been called one of Blomfield's most successful.  St John the Evangelist's Church, founded as a daughter church nearby in 1865, also continues to thrive as a separate parish church.  English Heritage has listed Christ Church at Grade II* for its architectural and historical importance.

St Mary's Church, Clophill: The present St Mary's Church is located in the centre of the small village of Clophill, between Bedford and Luton in the South Midlands of England.  The new church, built in 1848, replaced the old church by order of the Church Commissioners in 1850.  The old church building, formally The Church of St Mary The Virgin (shortened to The Church of St Mary) and known colloquially as Old St Mary's or The Old Parish Church, is at the edge of the village, and is estimated to be around 650 years old.  It sits at the crest of the Greensand Ridge, offering views over the surrounding countryside.  Its graveyard is a haven for wild flowers and wildlife.  After the church moved to the village centre, incorporating various items from the old church building, the old building was converted for use as a mortuary chapel, but in the 1950s it fell into ruin.

St Nicolas Church, Portslade: St Nicolas Church is an Anglican church in the Portslade area of the English city of Brighton and Hove.  It has 12th-century origins, and serves the old village of Portslade, inland from the mostly 19th-century Portslade-by-Sea area.
