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could not afford pew rents at the fashionable St Leonard's and St Mary Magdalene's Churches, the original building was superseded by a much larger church built next to it between 1873 and 1875.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 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. Historic England has listed Christ Church at Grade II* for its architectural and historical importance.

St Mary Magdalene's Church is a Greek Orthodox place of worship in St Leonards-on-Sea, a town and seaside resort which is part of the Borough of Hastings in East Sussex, England. Dedicated to Mary Magdalene and built in 1852 for Anglican worshippers in the growing new town of St Leonards-on-Sea, a seaside resort which had been laid out from the 1820s, the church's prominent position on the skyline overlooking the town was enhanced in 1872 by the addition of a tower. No longer required by the Anglican community in the 1980s, it was quickly bought by the Greek Orthodox Church and converted into a place of worship in accordance with their requirements. The alterations were minimal, though, and the building retains many of its original fittings and its "archaeologically correct Gothic" exterior which reflected architectural norms of the early Victorian era. English Heritage has listed the church at Grade II for its architectural and historical importance.
