Reference, evidence, and public education for the historic counties.

Historic counties are the enduring geography. Councils are administration, lieutenancies are ceremonial – neither define the counties.

County Geography

The Thames forms Buckinghamshire’s southern line against Berkshire for much of its length. To the west the county meets Oxfordshire, to the north Northamptonshire, and to the east Bedfordshire and Hertfordshire. The Chiltern ridge gives the south a strong internal structure, while the northern vale opens toward the upper river country.

The contrast between river frontage, chalk upland, wooded dip-slope, and open vale gives Buckinghamshire a distinctive composition.
