The parish settlements

Hartfield is the main village in the parish. The church is dedicated to St Mary the Virgin. There are three public houses: Anchor Inn; Gallipot Inn; and Haywagon Inn. The village street is narrow, precluding much parking although The Anchor and Haywagon Inns have private car parks for patrons only. Cotchford Farm, Hartfield was the home of A.A. Milne (1882”“1956), author of the Winnie the Pooh books, from where many of his books are set; later it was owned by Brian Jones the guitarist and founder of The Rolling Stones who was discovered dead in the pool in 1969. There is a shop in the village dedicated to all things connected with the Winnie the Pooh stories. Hartfield had a railway station on the Three Bridges to Tunbridge Wells Central Line until it was closed in 1967. Most of the former trackbed is now part of the Forest Way, forms part of National Cycle Route 21, and is much used by walkers and cyclists. The station building itself is now used as a pre-school. There is a bus service that connects the village with Crawley, East Grinstead and Tunbridge Wells. There are a number of businesses in the village.

Colemans Hatch
The hamlet of Colemans Hatch lies to the south-west of Hartfield. It is a scattered settlement around a series of road junctions. The church here is dedicated to the Holy Trinity and is part of the joint benefice with St Mary’s Hartfield. The Hatch Inn is located here. General Sir Reginald Hildyard (1876”“1965) lived at South Hartfield House, Colemans Hatch.

The name Hammerwood comes from the Wealden iron industry and relates to the numerous hammer-ponds found in the area. Streams in the locality can still run red with the colour of iron in the water. A hammer-pond is a water reservoir created specifically for providing power to water-powered hammers, forges or blast furnaces. There were many Medway watermills in the area. Aside from a number of houses, the most notable buildings are St Stephen's Church and Hammerwood Park at the end of the lane, which was the centre of what was a large country estate extending in its heyday to over 2,500 acres (10 km²). The church was completed in 1880 funded by local landowner Oswald Augustus Smith and built to a design of E.P. Loftus Brock. Smith also funded the rebuilding of St Peter's Church in Holtye within the same parish. The church can be found on the main road. Inside the church is a pipe organ built by T.C. Lewis of Brixton in 1884. There is a Scout campsite at Hammerwood owned and operated by the Lewisham North District Scouts. Hammerwood Park Hammerwood Park is a country house south of the village: it is Grade I listed of historical interest. Built in 1792, it was the first work of the architect Benjamin Latrobe, who was also responsible for the United States Capitol in Washington, D.C. It was one of the first houses in England built in the Greek Revival style. It was bought by the rock band Led Zeppelin in 1973, although not properly maintained by them. Left almost derelict, it was then bought in 1982 and restoration began: that restoration was award-winning and it received a lot of television coverage. The house is often used for filming, and is open to the public in the summer: concerts are often held there.

Holtye is immediately north-east of Hammerwood. Here the public house is The White Horse Inn; the church is dedicated to St Peter, although the church is now redundant.
