The architecture of Aylesbury, the county town of Buckinghamshire, reflects the ordinary architecture which can be found in many small towns in England where the buildings of the town were designed by local architects. This is characteristic of the built environment of Aylesbury, itself a good example of an English county town. The local architecture and vernacular buildings in the market towns were usually inspired at second hand by the work of the great master architects or the general architectural style popular at the time. England had a middle class long before many other European countries, these bourgeois merchants would often return from a visit to one of the cities, or having seen a glimpse of one of the great country houses then require a replica of what they had seen. A local architect would then be employed to recreate it, within limited financial restraints. Sometimes the patron would merely draw an image of what he required and a builder would then interpret the requirements to the best of his ability.
This percolation of architectural style was not confined to private houses, but to civic architecture too: an illustrious architect added to civic pride; and when an architect was too expensive for the civic coffers, for a fraction of the price he would judge a competition between local architects, for the privilege of designing a town hall or church. This is exactly what happened in Aylesbury. John Vanbrugh judged two sets of plans for the County Hall (now Aylesbury Crown Court). Thus for ever Vanbrugh's name was remembered in association with the building, the local architect almost forgotten, and civic pride maintained.
It is this provincial, often unappreciated and unnoticed architecture, by nationally unknown architects still being produced today which continues to give many English market towns their unique atmosphere and character, the architecture of Aylesbury demonstrates this admirably Aylesbury retains some buildings from the medieval, Stuart, Georgian and Victorian periods, as well as the 20th century. Ceely House, Ardenham House, the Union Workhouse and The County Gaol are among the most notable buildings in the town.
