Fairfax County Courthouse and Jail (Boundary Increase)
Also known as: See Also:Fairfax County Court House

Why it's listed
Fairfax County's old courthouse and jail stand together at 4000 Chain Bridge Road in the city of Fairfax. The courthouse was built in 1799-1800 from a design by James Wren, with James Bogue and Mungo Dykes as builders. It is a two-story Flemish-bond brick building with an arcaded gable end and an octagonal cupola, and it served as a prototype for other Virginia courthouses. Its history includes the Civil War years, when it lay near the front lines; its interior was gutted by 1862, and Confederate Colonel John S. Mosby raided the town in March 1863. Behind it stands the jail, built in 1885 after a fire, a two-story T-shaped brick building later enlarged twice. It served as a jail until the 1953 courthouse addition and since 1956 has housed county offices. The boundary was increased to include the jail while excluding the 1930 courthouse addition.
Significance in brief: The courthouse is significant architecturally as a transition between one-story arcaded colonial courthouses and later two-story Roman Revival examples, and historically for its role in the Civil War, including Mosby's 1863 raid. The 1885 jail is a Victorian-style building that adds to the complex as an expression of the county's continued growth.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
