Puddletown's parish church, dedicated to St Mary, has been described as being "of considerable architectural interest", "of exceptional interest for its furnishings and monuments" and "one of the most exciting parish churches in the county". It has 12th-century origins—parts of the tower date from 1180–1200—but was rebuilt and enlarged between the 13th and 16th centuries. The 12th-century font is particularly notable, being of a tapering beaker shape, with diapering depicting crossing stems and "Acanthus" leaves; its cover is an octagonal pyramid dating from about 1635, when the church interior was refitted. There is a panelled roof in the nave, and 17th-century box pews, pulpit and gallery. There are also a number of 15th- and 16th-century monumental brasses and some stained glass by Ninian Comper. The South or Martyn family chapel has three 16th-century tombs with alabaster effigies. In 1910 the church was partially restored by Charles Ponting. Thomas Hardy led an unsuccessful campaign to prevent enlargement of the original chancel.
