We were in Leesburg for a conference but took some time to visit the charming town. Even though the buildings were old they were, for the most part well kept and gave you the sense of having been transported to an earlier era.
Uneven sidewalk so take care if you are not steady. Found several old cemeteries, churches and houses to enjoy seeing. On this 10ish Sunday morning we found street parking. Later on the shops and galleries were open.
This is a charming town with many carefully preserved old buildings. There are several self-guided walking tours available online which guide and explain parts of the town. Enjoy!
