Leighton Buzzard (ˈleɪtən_ˈbʌzərd ) is a market town in Bedfordshire, England, in the southwest of the county and close to the Buckinghamshire border. It lies between Aylesbury, Tring, Luton/Dunstable and Milton Keynes, near the Chiltern Hills.
It is northwest of Central London and linked to the capital by the Grand Union Canal and the West Coast Main Line. The built-up area extends on either side of the River Ouzel (here about 2 metres wide) to include its historically separate neighbour Linslade, and is administered by Leighton-Linslade Town Council.
It is unclear when the town was initially founded, although some historians believe that there may have been settlement in the area from as early as 571. There are a number of theories concerning the derivation of the town's name; ‘Leighton’ came from Old English Lēah-tūn, meaning 'farm in a clearing in the woods', and ‘Buzzard’ was added by the Dean of Lincoln, in whose diocese the town lay in the 12th century, from Beau-desert. Another version is that having two communities called ‘Leighton’ and seeking some means of differentiating them the Dean added the name of his local Prebendary or representative to that of the town. At that time it was Theobald de Busar and so over the years the town became known as Leighton Buzzard. The other Leighton became Leighton Bromswold. In the Domesday Book of 1086, Leighton Buzzard and Linslade were both called Leestone.
Leighton Buzzard developed into a thriving market town supported by good road, canal and, later, rail links to the agricultural hinterland and London. The town's market charter was granted in 1086 and is still active today. The town's high street is home to numerous historical buildings, more than 70 of which are listed. They include the notable Bank Building on the Market Square (now home to Barclays Bank), designed by the eminent architect Alfred Waterhouse, designer of London's Natural History Museum, London. They also include the Old Town Hall, later used as a fire station and now as a restaurant.
