The red-brick Victorian station still stands on the VRE (Virginia Railway Express) commuter line, making it both a working rail station and a piece of 19th-century architecture worth a look. The building dates to 1914 — a rebuild of earlier structures — and is considered one of the better-preserved small-town depots in northern Virginia.
The station is within easy walking distance of Old Town. Trains run to Washington's Union Station on weekdays, making Manassas a plausible base for day trips into the capital if you want to avoid the city's hotel prices.
