London's River Lights

If you walk along the Thames Path, east of Woolwich, you will discover these small red lighthouses. They can be found at Margaretness (or Tripcock Ness), Crossness and Coldharbour.

They are not lighthouses, in the traditional sense, but more like navigational light masts.

The Margaretness Lighthouse was installed in 1902, by Trinity House (the General Lighthouse Authority for England), but has been operated by the Port of London Authority, since 1993. 

In 1566, Queen Elizabeth I empowered Trinity House to set up "so many beacons, marks and signs for the sea whereby the dangers may be avoided and escaped and ships the better come into their ports without peril."

Margaretness Pillbox

A World War II pillbox along the River Thames.

Walking along the Thames Path there is always something new to see or discover.

It was while walking east, from Crossness, that I first saw this World War II-era pillbox. It is typical of the time and was used as an observation post, with a wide 'window' which offered a wide field of vision.

There were many versions of pillbox design, with different areas and counties having their own specific design. This one was adapted, at some point, to be fitted with an anti-aircraft gun. This, obviously, has been removed.

This pillbox has a wide field of vision.

Brief History.

Pillboxes were small, hardened concrete bunkers with loopholes for firing weapons, designed as fixed firing positions. They were part of a network of defensive structures, built in the late 1930s and early 1940s, to defend against a potential enemy invasion and to protect key sites.
