Althorp is a Grade I listed stately home and estate in the civil parish of Althorp, in West Northamptonshire, England of about 13,000 acres. By road it is about 6 miles northwest of the county town of Northampton and about 75 miles northwest of central London, situated between the villages of Great Brington and Harlestone. It has been held by the prominent aristocratic Spencer family for more than 500 years, and has been owned by Charles Spencer, 9th Earl Spencer since 1992. It was also the home of Lady Diana Spencer from her parents' divorce until her marriage to Charles, Prince of Wales.
Althorp is mentioned as a small hamlet in the Domesday Book as "Olletorp", and by 1377 it had become a village with a population of more than fifty people. By 1505 there were no longer any tenants living there, and in 1508, John Spencer purchased Althorp estate with the funds generated from his family's sheep-rearing business. Althorp became one of the prominent stately homes in England. The palace dates to 1688, replacing an earlier house that was once visited by Charles I. The Spencer family amassed an extensive art collection and other valuable household items.
