Lower Horse

Lower Horse is a river island in the Thames Estuary lying between Canvey Island and Stanford-le-Hope. The island consists of permanent marshland crossed by six internal creeks that drain northward toward the main river.

The island separated from the English mainland during medieval times as part of the natural formation of Thames Estuary islands. Salt extraction was recorded as an activity here during the early 1900s based on historical maps.

Maps from 1919 document the island's salt extraction activities through the presence of saltings, marking a connection to traditional maritime industries.

The island is uninhabited and difficult to access due to environmental conservation regulations. Anyone wishing to visit must arrange special permission in advance.

The Essex administrative boundary runs between Lower Horse and Canvey Island, dividing these islands administratively. This invisible line marks an official division between two local jurisdictions in the river estuary.
