This beautiful Grade I-listed church in Rothwell in Northamptonshire dates from the the early 12th century. It is considered to be one of England's Thousand Best Churches and is renowned for many of its features, including its subterranean charnel chapel with its medieval ossuary (a collection of human bones). There are the skulls of some 2,500 people.
The Norman church survives in the chancel, but in the following centuries the church was greatly enlarged. In the early 14th century transepts were added on the south and north side although these were later demolished in the 17th century. The nave is currently the longest in Northamptonshire and at one time was even longer. At one time the church had a fine steeple, but this collapsed in 1660.
My sources included the National Churches Trust and Sir Simon Jenkins' book: England's Thousand Best Churches.
