Set in the historic Old Post Office Building, the Collin County History Museum is a landmark for anyone curious about the county's past. Its archives, family files and photographs support genealogy and family research, and the museum can arrange private viewings of exhibits and records.
The museum stands at 300 East Virginia Street, in the 300 block, at grid M13 on the printed downtown map. The courthouse square is about a 3-minute walk away. Hamm's Meat + Market, Donuts R More and Koji Sushi are nearby, so a visit here pairs well with a meal a short walk away.
