GE Street re-roofed the church and restored the north wall. In 1889 the rood screen and loft were restored. St Mary's has never been over-restored, and its Decorated and Perpendicular mediaeval character has survived almost intact. By 1553 the bell tower had five bells plus a Sanctus bell, but all have since been recast or replaced. Richard Keene, whose foundries included one at Woodstock, cast the two largest bells in 1681. Thomas Lester of the Whitechapel Bell Foundry cast another bell in 1746 and Matthew II Bagley of Chacombe, Northamptonshire cast another in 1755. The then treble bell broke in 1789 but John Warner and Sons of the Whitechapel Bell Foundry recast it that same year. In the 19th century the Bagley bell survived for a long time with a fracture, but in 1895 its tongue and head fell out. Mears and Stainbank of the Whitechapel Bell Foundry replaced or recast the broken bell in 1898. In 1998 the Whitechapel Bell Foundry cast a new treble bell, making the 1789 bell the second bell and increasing the tower to a ring of six bells. In 1999 the new bell was hung and the old bells re-hung as a project for the village to celebrate the Millennium. John Warner and Sons cast the present Sanctus bell in 1793. St Mary's church clock is of unknown date but appears to be late 17th century. Two of the wheels of the going train are characteristic of the work of the clockmaker and bellfounder Edward Hemins of Bicester, which would make them an early-18th-century alteration. St Mary's is now part of the Church of England Benefice of the Ray Valley. Baptist and Methodist chapels Charlton-on-Otmoor had a Baptist meeting house by 1810 and a chapel in 1835. The village also had a Methodist congregation by 1829 and a chapel in 1840. The Methodist chapel had ceased to be used by the end of the 19th century and was sold to the rector in 1920 for use as a club room. The Baptist chapel closed around 2010 and was later sold and converted to a residential property. Amenities Primary school The enclosure of 1858 set aside land for the building of a school and in 1866 Charlton Parochial School and a master's house were built, mostly at the expense of the rector. The number of pupils grew and a second classroom was added in 1892.
