Mersea Fort, also known as Cudmore Grove Blockhouse, was an artillery fort established by Henry VIII on the East Mersea coast in 1543. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended the River Colne that led to the town of Colchester. It was triangular in shape, with earthwork walls and three bastions to hold artillery. It was demobilised in 1552, but was brought back into use several times over the next century and saw service during the Second English Civil War of 1648. The fort hosted an admiralty court to oversea the local oyster trade, until the dilapidation of the site forced the court to move to the Moot Hall in Colchester in the middle of the 18th century. A new gun battery was built at the fort during the Napoleonic Wars, but the fortification then fell into decline and was extensively damaged by the construction of a sea wall along the coast. The remains of the earthworks were excavated by archaeologists between 2002 and 2003.

The River Colne ( or ) is a small river that runs through Essex, England and passes through Colchester. It is not a tributary of any other river, instead having an estuary that joins the sea near Brightlingsea. The river's name is of Celtic origin, combining the word for rock "cal" with a remnant of the word "afon", or river, giving the meaning "stony river". However, another authority states that the river's name was originally Colonia Fluvius, the "waterway of the Colonia": a reference to Colchester's status in Roman times. There are two other rivers in the UK that share the same name.

Mersea Island is an island in Essex, England, in the Blackwater and Colne estuaries to the south-east of Colchester. Its name comes from the Old English word meresig, meaning "island of the pool" and thus is tautological. The island is split into two main areas, West Mersea and East Mersea, and connected to the mainland by the Strood, a causeway that can flood at high tide. The island has been inhabited since pre-Roman times. It was used as a holiday destination in Roman Britain for occupants of Camulodunum (Colchester). Fishing has been a key industry on the island since then, particularly oysters, and along with tourism makes up a significant part of the island's economy. The Church of St Peter & St Paul in West Mersea is thought to have existed since the 7th century, while the Church of St Edmund in East Mersea dates from around the 12th or 13th century. The island became popular with smugglers from the 16th to the 19th century. It became a focal point for troops in both world wars, and a number of observation posts can still be found on the island. Tourism remains popular, and there are a number of beach huts and holiday parks on the island. A week-long festival of boat racing, Mersea Week, takes place every summer.

Fingringhoe is a village and civil parish in the City of Colchester district of Essex, England. The centre of the village is classified as a conservation area, featuring a traditional village pond and red telephone box. The Roman River flows nearby before entering the River Colne. It has been noted frequently on lists of unusual place names. The village's name actually derives from its geographic circumstances: it sits at the confluence of the smaller Roman River and the River Colne. A "hoe" refers to a jutting out piece of land while "finger" describes an elongated finger-like land extension. "Ing" is a common toponym in the UK referring to "peoples". As such, the name refers to the "people living on the land jutting out into the river".

The Roman River is a river that flows entirely through the English county of Essex. It is a tributary of the River Colne, flowing into its tidal estuary below Colchester. The lower end of the Roman River is also tidal, with tidal water flowing upstream to just above Fingringhoe. In the past, the river was important for milling. There was a tide mill at Fingringhoe, which was used between about 1520 and 1893, when it was replaced by a steam roller mill. Further upstream, Layer de la Haye Mill was a conventional watermill with a longer history, as the first mill on the site was mentioned in the Domesday book. It was a corn mill, but finished its working days grinding product for a mushroom farm, built nearby. There were two further mills on the river, of which all trace has gone. The Roman River has two major tributaries, the Birch Hall Brook and Layer Brook. The latter used to supply some of the water for Abberton Reservoir, through which it flowed. However, work to extend it began in 2009, and water from the upper Layer Brook is now pumped into the reservoir, because its level has been raised by 10.5 feet (3.2 m). The reservoir is of international importance for wildlife, and has several conservation designations to protect its status. The Essex Wildlife Trust operate a visitor centre near the raised dam, which enables visitors to see the large bird populations.
