St Guthlacs Church in Passenham is holding an Open Day on Saturday.
Visitors will be able to discover the Chancel wall paintings, stained glass windows and choir stalls, which date back to the early 17th Century.
These paintings were commissioned by the then Lord of Passenham Manor, Sir Robert Banastre, a much-hated landlord whose ghost is said to haunt Passenham to this day.
After being under a layer of whitewash for more than 200 years, they were discovered and restored in the 1960s and are the main reason the church is a Grade I listed building.
The building also contains highly unusual Jacobean box pews and an intricately carved gallery screen depicting some rather surprising activites (for a church!).
Entry is free but buy some refreshments as The Friends of St Guthlacs are trying to raise enough money to ensure this remarkable example of Anglo-Catholic church heritage is preserved .
Take a look between 11am and 4pm.
