The five City-owned historic buildings are Fairfax Elementary School, Old Town Hall, Ratcliffe-Allison House, Blenheim and Grandma's Cottage.

Old Town Hall is the social and architectural cornerstone of the City. Joseph E. Willard presented the Hall as a gift tot he citizens of Fairfax in 1900. Built by Arthur Thompson, a local contractor, the classical revival style Hall retains much of its original woodwork. Old Town Hall's second level houses the Huddleson Library and is home to the Fairfax Art League. The Hall is available for rental for wedding receptions and other gatherings. For information about reserving the Hall, email or call 703.385.7858

Built by Richard Ratcliffe in 1812, this house is one of the city's oldest residences. This house-museum interprets the daily activities of some of its twelve owners and occupants, illustrating commercial and domestic change along Main Street during the 19th and 20th centuries. The last two private owners were Kate Waller Barrett, prominent social reformer, and her daughter, Kitty Pozer. Pozer, a respected gardener, deeded the house to the city in 1973. The house is open to the public for free tours from 11 a.m. to 2 p.m. Saturdays from April through October, during many city special events, during walking tours offered in the spring and fall, and by appointment; email or call 703.385.8414

The City of Fairfax purchased the historic Blenheim estate in early 1999 to preserve and develop into a Civil War house museum and open-air park. Blenheim is a c.1855 central-hall-plan brick farmhouse on 12 acres located at 3610 Old Lee Highway. The site hosts the Fairfax Civil War Weekend held annually the first weekend in May. The property was added to the National Register of Historic Places in early 2001. It is nationally significant for the 100+ signatures, art, and poetry created by Union soldiers during their occupation of the Fairfax Court House area in 1862-1863. The house contains one of the most voluminous and best-preserved examples of Civil War graffiti in the nation, a "diary on walls" providing insight into typical soldier life during the Civil War. The site also includes a newly constructed 5,000-square-foot Civil War Interpretive Center with exhibits, an assembly hall, outdoor pergola patio, gift shop and restrooms that are all ADA-accessible. The Center is available for rental and has capacities of 110 standup, 72 seated, or 190 for an outdoor tented occasion. The Center is open Tuesday-Saturday from Noon-4pm with a 1pm site tour. The Blenheim house is only open during the 1pm site tour. For general site information call 703-591-0560, for rental information call 703-385-7858.

Grandma's Cottage is significant both for its architecture and history. The Cottage was occupied for much of its history by Margaret Conn Willcoxon Farr, the daughter of Rezin Willcoxon, owner of the Willcoxon estate (later named "Blenheim"). Margaret Farr is buried in the Blenheim cemetery. The Cottage likely dates to the 1830s or 1840s and is important for its combination of log-wall construction and rare hewn timber framing with brick infill between the studs in the oldest portion of the house.

The Cottage's original location was near the corner of Main Street and Old Lee Highway where the Main Street Marketplace shopping center stands. It was relocated from there to a location on Old Lee Highway near Layton Hall Drive in 1962. The Cottage was moved to the Blenheim estate in 2001.
