No documentary evidence has been found to show how James Wren evolved his design for the Fairfax County Courthouse; but it seems probable that he knew of this style that was enjoying current popularity in England, and that John Bogue, the "undertaker" who built the courthouse, was familiar with the methods of constructing such buildings, for Bogue had just come to America from England in 1795. While the similarity of geometric and structural exterior design strongly suggests that the Fairfax County Courthouse had its architectural ancestry in the English town halls of that period, the analogy is weaker when functions are compared. The courthouse for Fairfax County was designed and used entirely as the seat of local government. The commercial activity that was attracted to the courthouse site on "court days" enjoyed no special privileges or facilities in the building. In contrast, town halls in eighteenth century England often served the dual purpose of providing a facility for transaction of public business and carrying on the commerce of the community. The style of the English town halls provided space in the open arcade of the ground floor to house a farmers' and tradesmen's market, and space in the second floor chamber for the town council to meet and do its work.[149] The origin of this type of building is not entirely clear. It is difficult to imagine it growing naturally in the political and social climate of the villages which grew up clustered around England's medieval castles and monasteries. At the time when town-and-market halls were common in the central squares of free towns in Italy, Germany and the Low Countries, they were absent in England. Their appearance in England dates from the seventeenth century when town government developed its own identity, and when British political and cultural alliances with the Dutch were established.[150] Imported to Virginia as a form of courthouse building, this town hall style became a popular prototype for buildings erected in several counties during the first three decades of the nineteenth century. After being introduced in Fairfax County in 1800, this style appears in the Nelson County Courthouse built in 1807, the Caroline County Courthouse built in 1808, the Sussex County Courthouse built 1825-28, and the Madison County Courthouse built 1829-30. Variations in the layout of the interior appeared in the use of the space over the arcade; sometimes it was used for the jury room, and at other times it was used to accommodate a balcony for spectators.[151] After 1824, however, a new style of courthouse building may be seen in the public buildings of Virginia counties. Based on the neo-classical lines of the State Capitol, designed by Thomas Jefferson, there came into being a series of courthouses which were suggestive, if not actual, representations of the seat of state government.[152]
