The Port of Tilbury is located on the River Thames at Tilbury in Essex, England. It is the principal port for London; as well as being the main United Kingdom port for handling the importation of paper. There are extensive facilities for containers, grain, and other bulk cargoes. There are also facilities for the importation of cars. It forms part of the wider Port of London.
The Port of Tilbury lies on the north shore of the River Thames, 25 miles (40 km) below London Bridge, at a point where the river makes a loop southwards, and where its width narrows to 800 yards. The loop is part of the Thames lower reaches: within the meander was a huge area of marshland. Gravesend on the opposite shore had long been a port of entry for shipping, all of which had used the river itself for loading and unloading of Cargo and passengers. There was also a naval dockyard at Northfleet. The new deepwater docks were an extension of all that maritime activity.
