The tiny but picturesque hamlet of Burgh-by-Sands is just another dormitory village for nearby Carlisle, but in the middle of the village a sign points north to "Edward I Monument". If you follow the sign you are guided to where the road peters out into a farm track. The adventurous leave their cars and walk for ten minutes or so down the slope to the wide expanse of Burgh Marsh, where a solitary pillars stands in splendid isolation.
This film tells you why this pillar stands in England's most northerly point, for on the other side of the Solway Firth Scotland begins.
The "More info" option takes you to an authorative biography of Edward I; a less favourable (and probably less scholarly) account of the king is given in The Brothers Gwynedd by Edith Pargetter. Needless to say, it is a view that any good Welshman would enthusiastically endorse.
