Glapthorn is approximately 1+1⁄2 miles NNW of Oundle, the closest town. North of the village is a small wood, Short Wood, with a Saxon earthwork. After suffering problems from widespread "Dutch Elm Disease" tree infection in the 1970s, the woodland is recovering its attraction and is particularly known for its May-time display of bluebell-carpeted open coppice. There are many other species in the woodland, resulting in it being classified as a SSSI. It is publicly accessible as a nature reserve.
Glapthorn's church of St Leonard's mostly dates back to the 13th century with the porch and south doorway added in the 14th century. The altar rail and panels in the pulpit were installed during the reign of James I. Other noteworthy items are a Victorian bier, an original pew located at the back of the church, three bells (one of which dates to the 14th century by John Sleyt), and an organ. The church retains traces of medieval paintings of what is believed to be St. Christopher.
