....and did those feet in ancient times......

A Clapper Bridge at Penponds, Cornwall. This is a Grade II listed building. Planning approval for demolition and subsequent erection of a bungalow has not been approved. :-)) (My appalling idea of humour)
From the English Heritage site.
Public footbridge over stream. Probably early C18 or earlier. Granite.
Clapper bridge type, with 3 flat spans formed by roughly-hewn stone planks
in pairs tied together with iron staples and supported by 2 hefty blocks set
in the bed of the stream. On the south side is a simple iron handrail
supported by 4 very slender iron posts. A rare survival.


Before the presence of a main road over the stream this was the route taken daily by miners. As can be seen it is a rare survivor; so much so that it is the image used on the village school sweatshirts. 


The word 'clapper' derives ultimately from an Anglo-Saxon word, cleaca, meaning 'bridging the stepping stones';[2] the Oxford English Dictionary gives the intermediate Medieval Latin form  clapus, claperius, "of Gaulish origin", with an initial meaning of "a pile of stones."


Extra, another view, not quite in focus, it was raining and I'm.....well I am. :-)
