The Buildings

Headstone Manor is a complex of four historic buildings set in beautiful grounds, including a 14th century complete and filled moat.

Headstone Manor House

Built in around 1310, Headstone Manor is the earliest surviving timber framed house in Middlesex. The fabric of this Grade 1 listed building contains work dating from the 14th, 17th and 18th centuries. Headstone Manor has been described as
‘one of the most interesting domestic complexes in the whole country’.

The Manor House now contains the museum at Headstone; telling the history of Harrow through the house and the people who have lived there over its fascinating history.

The Great Barn

The Grade II 500-year-old Great Barn was used to store grain and livestock when Headstone Manor was a working farm. It was also the center of local home front activities in the area during World War II as well as the first home of the museum in the 1980’s.

Today it is used as a spectacular venue for weddings, parties and special occasions. To find out more information about hiring the venue please visit The Great Barn (opens in a new window).


The Small Barn

The Small Barn stands opposite The Great Barn and is a Grade II listed building. It also dates back to the Tudor period, when it would have been used to house livestock.

It now houses the entrance to the museum, exploring the history of Harrow before The Manor House was built, as well as a short film introducing the site.

The Granary

Dating from the early 19th Century, the Granary was originally constructed at Pinner Park Farm. The building was relocated to the Headstone Manor and Museum site in 1992.

The Granary is now our dedicated learning center, a space for schools sessions, family and adult learning. When the building isn’t in use by a group you can use our free art cart and get crafty downstairs in The Granary.
