St. Pancras Old Church has been a site of Christian worship since the fourth century. Although there are some ancient parts of the building dating back to the 11th century the majority of the structure was rebuilt in the 19th century following a period of dereliction. It is a grade II listed building.
The church is open regularly for visiting and the surrounding churchyard is a peaceful and beautiful place with many interesting monuments to peruse. The architect Sir John Soane is one of a number of notables whose remains are burried here, and to whom monuments may be seen. Parts of the churchyard have been cleared of monuments to make for a park-like atmosphere.
