Chiswick Eyot

Chiswick Eyot is a 3.266-acre narrow, uninhabited ait in the River Thames. It is a tree- and reed-covered rise on the Tideway by Chiswick, in the Borough of Hounslow, London, England and is overlooked by St Nicholas Church, Chiswick, the Mall of Hammersmith and by some of the Barnes riverside on the far bank. Excluding tidal mudflats and sandbanks, it is the most downstream island purely on the Thames itself .

It is beside The Championship Course and marks the approximate half-way point of The Boat Races races) and the country's international Head of the River Race among others. A green pole stands on one end used for timings by rowers of that course, at the southwest, church end of the island. Small craft can pass between it and Chiswick Mall on the Middlesex bank for about two hours at high tide, but the small channel is generally impassable otherwise — at low tide it is possible to walk to it as it is a tidal island.
