Description

Grantham House is a historic building dating from the 14th century, with remodels and additions from the 16th century, including a chimney stack dated 1574. The south front was redesigned around 1735 and features a well-proportioned symmetrical elevation that incorporates some mid-17th century windows. The north front retains many 16th century characteristics. Inside, there are panelled rooms from various periods, a notable mid-18th century staircase, and traces of 16th century work. The house was once known as Hall Place, named after the Hall family who lived there in the 16th and 18th centuries, and it was later occupied by members of the Cust family. It has recently been handed over to the National Trust. The drawing room includes a fireplace from a demolished house of the same period in Newark. Grantham House was the home of Arthur Hall, an Elizabethan translator of the "Iliad."
