Why is it useful to use code when dealing with dates? There are good reasons, and the Generation/ Year/ Month/ Day code is a simple and effective way to do it. Find out about the GYMD code.

There were once many hundreds of milestones and mileposts in the county of Essex. Against all the odds, about half of them have survived through the centuries and are still to be found today. My milestone map plots the lot. Find out about the Essex milestone map.

Berkshire is another county with a fine population of surviving mile markers. This map shows them and the location of lost markers for the whole of the historical county, and a bit of North Hampshire as well. Find out about the Berkshire milestone map.

WORK IN PROGRESS. This map will show the location of surviving and lost mile markers for the whole of the historical county of Oxfordshire. Only about three-quarters has been done so far, but you're welcome to see what there is. Find out about the Oxfordshire milestone map.

Less well known than milestones, other distinctive markers were used to define the boundaries of some counties. Berkshire is one of these. The borders of the modern county with Wiltshire, Hampshire, Surrey, Buckinghamshire and Oxfordshire were surveyed between 2006 and 2009. Find out more about Berkshire boundary markers.

Thanks to John Nicholls, the Milestone Society's Essex representative (working well away from home) we now know a lot more about the county boundary markers of Buckinghamshire as well. I've provided web space and drawn the map, but he's done all the real work. Find out more about Buckinghamshire boundary markers.
