Chew Magna, United Kingdom

According to Robinson its manors, lay and religious holdings formed an episcopal property held, as overlord, by Giso, the last Saxon bishop and the name Magna comes from the Latin meaning 'the greater'. This is supported by the Domesday Book which was made to specify the 1086 and the pre-conquest holder, in both instances given as the "Bishop of Wells". Hence its benefice was from the early medieval period converted from a rectory to a vicarage, with substantial tythings adjoining named Bishop Sutton, Knowle with Knighton Sutton, North Elm, and Stone. Furthermore, it had the living of Dundry annexed to it. By 1848 all tithes had been commuted and the sole impropriator is listed in 1848 of the great tithes as George Smyth.

In the eastern corner of the south aisle of the church is a monument of the Baber family, who formerly had large possessions in the parish. Inserted in a window of the aisle, is a wooden effigy, supposed to be of Sir John de Hautville, a Knight of Henry III's, who owned the northeastern estate named Norton Hautville, now Norton Hawkfield: in the same directional corner of the church are monuments to the Strach(e)y family who lived at Sutton Court.

A c. 13th-century carved sundial is still visible, although eroded, to the right of the church's door, and can be used to tell the time by carefully inserting a small stick to act as a gnomon. Midday is marked by a vertical line; post-meridian hours are to the right of this line.

Since about 1600, the name changed to Chew Magna as this has been the most important of the several villages along the banks of the River Chew and reflecting the reduced wealth of the established church from the Dissolution of the Monasteries onwards.

Around 1700 the Lord of the Manor was Sir William Jones, the Attorney General of England and in the 1820s it was the seat of Lord Lyttelton.

Until about 1880 the village had toll roads and a toll house to collect the fees.

By 1848 the population was partly employed in coal mines in Bishop Sutton, and in the manufacture of stockings and of edge tools to a limited extent; formerly there was a factory for cloth.

During the late 19th and 20th centuries the importance of the wool trade in the village declined and it became largely a dormitory area for the cities of Bristol and Bath, although it has continued to be the commercial centre of the valley throughout the decades, including the villages renowned Fairfield Nursery, managed by the Hiron's.

During German bombing raids targeted on Bristol, many bombs fell in the parish: Ruen House on the road to Chew Hill was bombed. The nearly flat area just east of the Y-junction on Chew Hill was initially chosen as a Starfish site area to be lit by fires to simulate Bristol in flames. Later, about halfway between North Chew Farm and Manor Farm, North Wick was an area secured by Royal Air Force personnel, lit by fires, and with "automatic" guns to simulate anti-aircraft guns. There was also a genuine heavy anti aircraft battery at Chewhill farm. The area was guarded by pill boxes of which one remains on the west side of Blacklands (map reference ST579640).

The construction of Chew Valley Lake in the 1950s brought opportunities for leisure and tourism.

On 10–11 July 1968 a storm brought heavy rainfall to the Chew valley and Dundry, with 175 millimetres (7 in) falling in 18 hours on Chew Stoke, which is double the area's average rainfall for the whole of July. This caused flooding to 88 properties in Chew Magna with many being inundated with 8 feet (2 m) of water. The bridge on the road to Dundry was demolished.

The Chew Magna telephone exchange was manually operated until the 1950s. An important number Chew Magna 2 was that of Dr Terrell Hughes: the exchange operators could often locate him in an emergency even if he was away from his home and surgery. The manual exchange served most of the Chew valley and even East Dundry.
