Greenway House

Summary

A Georgian country house overlooking the River Dart in Devon, partly constructed using materials reused from the earlier Tudor mansion on the site, built by the Gilberts of Compton Castle, one of the most prominent families in Elizabethan Devon. Its richly detailed interior was restored by Dame Agatha Christie, the internationally celebrated crime writer, and her husband, Professor Sir Max Mallowan, a highly influential archaeologist specialising in the Ancient Near East. The house’s architectural quality and exceptional level of survival are rare for a building of this type and age. Greenway House retains very high cultural significance as the inspiration of some of Christie’s writing and as a ‘time capsule’, with carefully curated interiors that reflect aspects of the national story from the 16th century through to the Second World War.

Reasons for Designation

Greenway House, Galmpton, Devon, is listed at Grade II* for the following principal reasons:

Architectural interest:

* as a well-executed Georgian country house, thoughtfully extended and partly remodelled by successive owners, including a mid-C20 restoration by Agatha Christie and Max Mallowan with the assistance of architect Guilford Bell;
* for the retention of the original Georgian plan form and design, and its construction in high-quality materials with interiors of good craftsmanship, including mahogany doors and panelling, an elegant principal stair, marble chimneypieces and timber casement windows with rebated shutters and other joinery;
* for the survival of fabric from Greenway Court, notably the C17 overmantel in the Winter Dining Room.

Historic interest:

* for its association with the C16 Greenway Court, a seat of the Gilbert family of Compton Castle, with some fabric reused in this late-C18 house. Sir Humphrey Gilbert, who was born at the Court, was a prominent figure in English colonial expansion in Ireland and North America;
* as a site of sustained local prestige over an extended historical period, reflecting ownership and occupation of a series of notable Devonshire and Cornish families through to the C20;
* for its strong association with Agatha Christie, a native of the area, who occupied Greenway as her country residence for around forty years. Her enduring international legacy lies in her crime novels, which are unrivalled in the way they capture the complex social mores of the early- to mid-C20;
* for its association with Max Mallowan, eminent British archaeologist of the mid-C20 and authority on the ancient cities of Ur and Nimrud;
* additionally, for the narrative frieze in the library, painted by a United States Coast Guard officer billeted at the house prior to the Normandy landings. Depicting the progress of the 10th Flotilla from Texas to Devon, including enemy engagement.

Group value:

* for its contribution to a consciously planned ensemble of buildings within the Greenway Estate, demonstrating strong historical and functional relationships with the other listed buildings of the estate.

History

The peninsula on the north bank of the River Dart, on which Greenway House stands, has a long history of occupation. A Tudor mansion known as Greenway Court was built there in the early C16 by the Gilberts of Compton Castle, a prominent seafaring Devon family. It was the birthplace of Sir Humphrey Gilbert (1539-1583), one of the ‘West Country Men’ who were prominent figures in English colonial expansion in Ireland and North America. He fought in Ireland and attempted to establish a colony using terror tactics in the 1560s and 1570s, and claimed Newfoundland for England in 1583.

Around 1700, the Greenway estate passed out of the Gilbert family. In the late C18, Roope Harris Roope built the current Greenway House. Archaeological investigations suggest that part of the west wall of the service wing was constructed on a cellar wall of the Tudor building, and some masonry from the earlier mansion was likely used in Greenway House. A painting by William Payne, dating from around 1788, depicts both the new house and the ruinous Tudor mansion; the latter was demolished shortly after Edward Elton purchased the estate in 1791. The C17 overmantel in the Winter Dining Room, which depicts a biblical scene of Shadrach, Meshach and Abednego in the fiery furnace, is also thought to have originated from the Tudor mansion.

Ordnance Survey maps of 1803 and 1809 show Greenway House with walled gardens to the north. The east and west wings of the house were added for Elton in 1815, along with a coach house and stables (listed at Grade II) to the north-west. The 1839 tithe map for Churston Ferrers Parish shows the estate under the tenure of Colonel Edward Carlyon, including other estate buildings such as the entrance lodge and boat house (also listed at Grade II). In the mid- to late C19, the estate changed hands several times. In 1892, under Thomas Bolitho of Trewidden, Cornwall, a further east wing was added, and the pleasure grounds were developed with extensive collections of rhododendrons, camellias, and magnolias. The house, associated buildings, and formal gardens are shown on the Ordnance Survey Map of 1904.

In 1938, Greenway was purchased by ‘Mrs Max Mallowan’, better known as the celebrated detective fiction author Agatha Christie (1890-1976), who had been brought up in nearby Torquay. Christie and her archaeologist husband, Max Mallowan (1904-1978), made a number of changes to the house and grounds, restoring its Georgian character with the assistance of the Australian architect Guilford Bell, including the demolition of the late-C19 east wing extension, which was replaced by a rear lobby. By this time, Mallowan’s work in Iraq and Syria had established his reputation as an innovative and influential archaeologist, and he became the published authority on the ancient city of Nimrud. Christie accompanied him on many of his excavations, herself becoming knowledgeable and experienced in archaeology. These experiences inspired some of her writing, notably Death on the Nile (1937). Many rare finds from the digs were stored and displayed at Greenway House, which itself inspired other works and features in two of her novels, Five Little Pigs (1943) and Dead Man's Folly (1956).

At the outbreak of the Second World War, Greenway House was requisitioned to accommodate child evacuees. In 1944, it was used by the United States Coast Guard during preparations for D-Day. During this time, some alterations were made to the house, such as the addition of bathrooms, which were later reversed by the Admiralty. However, a decorative narrative frieze painted in the library by Lieutenant Marshall Lee, which traces the journey of the 10th Flotilla from Texas to Devon via enemy engagement in Italy, was retained at Christie’s insistence as a ‘historic memorial’.

In 1947, a commercial nursery was established in the walled gardens, managed by Christie’s son-in-law, Anthony Hicks. The estate was sold to Mrs Hicks in 1959, following which some alterations took place, including the subdivision of the rooms to the second floor. Ownership of the estate passed to the National Trust in April 2000, and in 2005, the house, along with all of its contents, was given to the Trust. A subsequent conservation project used a 1942 inventory to return furniture and fittings to their original positions from Christie’s time. The upper floors of the house and the rear wing were adapted to visitor and staff accommodation.

Since 2009, Greenway House has been open to the public on selected days. Its layered history has been curated to reflect the profound global transformations and social changes that Christie witnessed during her lifetime. Objects and inspiration from Max Mallowan’s archaeological digs, most notably in Iraq at the site of the ancient city of Nimrud, where Christie frequently accompanied him, feature prominently in the house collection.
