Isaac Newton was baptised in the church in 1642 and his parents are both buried there. Of course, Newton is buried in the much more prestigious Westminster Abbey, but the church still contains remnants from his childhood. There is a copy of his baptism records on display and, partially obscured by the organ, is a sundial, which was carved by Newton when he was a child. Aside from the connection with the famous genius, the church itself has many interesting features.
A church has been located on the site for over 1300 years and this long history is evident in the Saxon stonework contained in the nave, as well as the remains of a Saxon cross, which is displayed at the entrance to the church.
Apart from the Saxon influence, the Normans, Victorians, and even Civil War soldiers have left their mark on the building. The Victorians extensively renovated the church transforming it from a 'hideous barn-like construction' into the present structure. A rood screen was partially destroyed by soldiers during the unrest of the 1640s and is on display behind the pulpit. Also of interest are the beautiful stained glass windows.
The church is not very large and its landmarks can be quickly toured. However, it is worth visiting for its connection to Newton, especially as part of a day trip to the larger Newton estate. Colsterworth is outside of Grantham, about one hour from Nottingham.
