Hidden London Guide

Three Mills Island: Hidden Gem Guide

A historic mill complex hidden near the Olympic Park waterways.

Three Mills Island, on the River Lea, is a rare survival of industrial London: historic tidal mills, cobbled streets and riverside paths, close to the Olympic Park.

The story

Mills have stood on this stretch of the River Lea for centuries. The two surviving mills are the House Mill, built in 1776 and the largest surviving tidal mill in Britain, and the Clock Mill, built in 1817. They ground grain, much of it for gin distilling.

Today the island is a conservation area. Three Mills Studios, in former industrial buildings, is a busy film and television studio. The river paths link to the Queen Elizabeth Olympic Park and the Lea Valley.

What to look for

  • The House Mill and Clock Mill.
  • The cobbled streets and old buildings.
  • The tidal river and locks.
  • The Miller's House café.

Why it's worth seeking out

Three Mills Island is a rare survival of the industrial landscape that once lined the River Lea. The mills, the cobbled streets and the old buildings give a sense of how the area looked before the docks and factories closed. The tidal river and its locks show how water was used for power, and the island is a good starting point for walks along the Lea to the Olympic Park or the Thames.

Combine it with

Bow Creek Ecology Park, Cody Dock and the Queen Elizabeth Olympic Park are nearby.
