The town has three notable churches. St Augustine's is part of the Catholic Archdiocese of Southwark and England's shrine to St. Augustine of Canterbury, whilst St Laurence and St George are both Church of England, and serve the Anglican community as part of the Diocese of Canterbury. Other churches include Holy Trinity and St Ethelbert's RC.
The first building used for worship in the Thanet parish of 'St Lawrence' was at St Laurence-in-Thanet, built in 1062 and rebuilt during the following centuries with the most significant changes being in the 16th century. Note the difference in spelling between that of the Village of St Lawrence and the church, which is dedicated to the Roman Martyr, Laurence.
A notable burial in the churchyard is Augusta Emma d'Este (1801–1866) wife of Thomas Wilde, Lord Chancellor and 1st Baron Truro. She is interred in the D'Este mausoleum.
The second notable church is St Augustine's, Ramsgate, which is situated on the town's westcliff. The architect, A. W. N. Pugin, built the church at his own expense between 1845 and 1852 in the neo-Gothic style and wrote that 'not one of the true principles will be broken'; it is considered one of the most important of Pugin's buildings. Pugin and other members of his family are buried in the chantry chapel in the church. The church's dedication commemorates Augustine, the first Archbishop of Canterbury, who landed at Ramsgate in AD 597 bringing Christianity to Britain for the first time since the Roman Empire. Pugin donated the church to the Catholic Archdiocese of Southwark before his premature death in 1852. In March 2012, the church was designated a shrine of St. Augustine of Canterbury; this ended a five-century absence of a shrine to St. Augustine as the original (at St. Augustine's Abbey, Canterbury) was destroyed during the Reformation.
