High Halstow is a village and civil parish on the Hoo Peninsula in the unitary authority of Medway in South East England. It was, until 1998, part of Kent and is still ceremonially associated via the Lieutenancies Act. The parish had a population of 1,781 according to the 2001 census.
Originally known as Hagelstowe, Hagelsto or Agelstow, it was named from an Old English word denoting a high, holy place. The area has been occupied by Romans, Saxons and Normans.
The village lies on the junction of the ancient roads from Hoo and Cliffe to the Isle of Grain, now a crossroads to the north of the A228 road. One of the highest points on the Hoo peninsula, at 30 to 50 metres above sea level, the modern village consolidates into a single community the four hamlets of Clinch Street, Fenn Street, Sharnal Street and High Halstow Street.
The 10th-century Grade I listed church of St Margaret at High Halstow was mentioned in the Domesday Book of 1086, and was built on the highest point of the Hoo Peninsula, overlooking the rivers of the Thames and Medway.
In the 18th century poverty and malnutrition were widespread across the peninsula, with High Halstow no exception; adult life expectancy was then about 30 years, lessened by ague, or marsh fever, the names for malaria, which proliferated in the North Kent Marshes and waterlogged farmland, a stronghold of the mosquito. The cause of malaria was discovered in 1890, and within five years the number of people falling ill with the disease decreased sharply as farmland and marshes were drained. This task was performed in no small way by Henry Pye, after he moved to the area.
The village remained small until after the Second World War, comprising the church, a school, two shops, a pub, a wheelwright's shop, and an undertaker's, with the village being served by a single policeman. Eventually some of the older houses were demolished and replaced. Churchill Place was developed and in the area behind the church, formerly known as the Square, several modern bungalows replaced five thatched cottages. From 1952 more homes were built in the village to house Isle of Grain oil refinery employees.
Historically, the main economic activity around High Halstow has been farming, but some of the village's residents gained employment outside the village, at the Royal Naval Armaments Depot at Lodge Hill, Chattenden, and the Medway Oil and Storage Co at Grain. Chatham Dockyard and the Short Brothers seaplane works at Rochester were also traditional employers for the whole area until they shut many years ago.
In 1956 a new school opened, the old school building being demolished along with Hill Farm to make way for additional housing. Building development has continued intermittently, including the new estates of Northwood Park and Heron Fields, development of which began in 1998.
The village still has its church, a shop and pub (the Red Dog) but has changed beyond recognition in living memory.
The village's cricket club has played in the area for almost 120 years. Ever expanding, the club now has Three Saturday sides, one Sunday side and three colts sides. They play their home matches at Rayner's Meadow, which is situated in Christmas Lane, and at the Hundred of Hoo school, Hoo.
