The parish church, called St Michael and all Angels, is a former chapel of a parent church at Badby. The benefice has always been Badby-cum-Newnham, with the vicarage of Badby. As the church is perched high on a bank, the churchyard descends steeply east and south. The chancel, the north aisle and the present nave were built in the early 14th century, on the site of a 12th-century chapel. The western tower was built in the late 14th or early 15th century abutting the west wall and standing on three open arches. The tower has contained six bells since 1660. They were rehung on a new iron frame by John Taylor & Co in 1940.
Other village amenities
On the village green can be found the "Mace" branded general store that supplies a wide range of goods and services, its post office counter closed in October 2008. Also on the green is the Romer Arms, a public house which was originally called the Bakers Arms. It was bought by a man named Romer Williams, who was a hunting man and a lawyer by profession.

At the summit of Newnham Hill near the edge of Beggars Bank is the village's most complete and prominent reminder of the rural industries. It is believed that a windmill has stood at this location as far back as 1661, when it was first recorded in an inventory of the then miller, John Bignell. The current building dates back to the early 19th century and was three floors high. The building was in a state of disrepair until the 1980s when a group was formed to repair and reconstruct the damaged building. Keys can be obtained to view the windmill by appointment through Daventry Tourist Information Centre.
