List of local nature reserves in Essex

Essex () is a county in the East of England. One of the home counties, it borders Suffolk and Cambridgeshire to the north, the North Sea to the east, Hertfordshire to the west, Kent across the estuary of the River Thames to the south, and Greater London to the south and south-west. There are three cities in Essex: Southend, Colchester and Chelmsford, in order of population. For the purposes of government statistics, Essex is placed in the East of England region.There are four definitions of the extent of Essex, the widest being the ancient county. Next, the largest is the former postal county, followed by the ceremonial county, with the smallest being the administrative county—the area administered by the County Council, which excludes the two unitary authorities of Thurrock and Southend-on-Sea. The ceremonial county occupies the eastern part of what was, during the Early Middle Ages, the Anglo-Saxon Kingdom of Essex. As well as rural areas and urban areas, it forms part of the wider Home Counties of England.

The Chelmer and Blackwater Navigation is the canalisation of the Rivers Chelmer and Blackwater in Essex, in the east of England. The navigation runs for 13.75 miles (22.13 km) from Springfield Basin in Chelmsford to the sea lock at Heybridge Basin near Maldon. Initial plans faced spirited opposition from Maldon, which were overcome by avoiding the town and terminating at Heybridge, and the navigation opened in 1797. There were some teething problems, and the engineer John Rennie was called back on two occasions to recommend improvements. The impact of the railways was less severe than on many canals, as there was never a direct line between Chelmsford and Maldon. The sea lock at Heybridge was enlarged after the Second World War, but trade gradually declined and ceased in 1972. Unlike most canals, it was not nationalised in 1948, and remained under the control of the original company. The first leisure boats to use the navigation did so in 1973, when the Inland Waterways Association organised a rally at Chelmsford. Springfield Basin was restored in 1992, but the proprietors faced bankruptcy in 2003, and after two years of negotiation, Essex Waterways Ltd, a wholly owned subsidiary of the Inland Waterways Association, took over responsibility for management, although the proprietors retained ownership. Because Essex and Suffolk Water abstract water from the navigation to supply Hanningfield Reservoir, they have a statutory obligation to maintain the outer gates at Heybridge sea lock, to prevent salt water entering the drinking water supply. They undertook major refurbishment work at the lock during the winters of 2016/17 and 2017/18, including replacement of the outer sea gate with a new design. A long-standing ambition, first proposed in 1985, has been to provide a better destination at Chelmsford, by providing access for boats to the town centre. A proposed link from Springfield Basin has been thwarted by road building in the area, but a plan to replace the automatic weir below Chelmsford Town Centre with a new structure incorporating a navigation lock was recommended in 2020.

Little Baddow is a village to the east of Chelmsford, Essex.

Hatfield Peverel Priory (also known as Hatfield Priory) was a Benedictine priory in Essex, England, founded as a secular college before 1087 and converted into priory as a cell of St Albans by William Peverel ante 1100. It is in the English Heritage Register of Parks and Gardens of Special Historic Interest in England and is located on the south side of the village of Hatfield Peverel, about 5 miles north-east of Chelmsford. At the Dissolution of the Monasteries, a timber-frame structure dominated the property.According to tradition the priory was founded by the Saxon Ingelrica, wife of Ranulph Peverel and reputed to be the mistress of William the Conqueror, to atone for her sins. The parish church, St Andrew's (Church of England) is the surviving fragment of the Norman priory church nave. The property was acquired by the Wright family when John Wright, a coachmaker, first landed his family in Essex in 1764. The current house, in a park designed by Richard Woods in 1765 and built in 1769, stands on a rise of land overlooking the Chelmer valley. The property passed to Wright's son, John Wright II, who died in 1796 without a male issue. The estate then passed under entail to his nephew (i.e. his sister's son) Peter Luard, who took the name and arms of Wright as required under the will. Peter (Luard) Wright, elder brother of William Wright Luard of The Lodge, Witham (and father of Admiral William Luard), occupied and expanded the property considerably. John Wright V, having suffered financial difficulties, in 1912 let the estate to Philip Charles Tennant (1867–1936), 7th son of Robert Tennant (1828-1900) of Chapel House in the parish of Conistone, Yorkshire, Member of Parliament for Leeds from 1874 to 1880. Tennant eventually purchased Hatfield Priory in 1928, following the death of the widow of John Wright V. In 1935, one year before his death, Tennant sold it to the Marianhill Mission, a Catholic lay brotherhood, which made it their European headquarters until their closure in 1972, when the property, now with derelict grounds, was purchased as a speculation by Dolph Claydon, a property developer, who quickly sold it on to Derek Marriott who used it as a school, which closed in 1979. In 2000 the property was owned by Adrian and Fiona Cowell, who have undertaken much restoration to house and grounds.
