Buckinghamshire
Buckinghamshire is a county of south-eastern England, located north west of London and often considered one of the Home Counties. It is bordered by Middlesex, Berkshire, Oxfordshire, Northamptonshire, Bedfordshire and Hertfordshire. The county town is Aylesbury. Buckinghamshire consists of three distinct zones: a belt of commuter towns (such as High Wycombe, Beaconsfield, Chesham, Amersham and Chorleywood) in low-lying or undulating terrain closest to London; the Chiltern Hills, a chalk ridge running SW-NE across SE England which is heavily wooded and scored by numerous steep-sided valleys; and Aylesbury Vale, an agricultural plain NW of the Chiltern escarpment. The new city of Milton Keynes lies in the north of Buckinghamshire (since 1996 this has been a Unitary Authority outside the administrative county).
