Lonely Planet review
The centrally located Archaeological Museum , built over a Roman villa’s remains, contains tombstones and votive tablets, plus the original villa’s mosaic floor. Sandanski’s apparent link to Spartacus is explained (in Bulgarian), and items from the adjacent ruins of the 5th-century Sveta Ioanna Basilica are also displayed. The basilica ruins themselves are small, but fun to wander around. Much less prominent Byzantine ruins are up on ul Mara Buneva, possibly including a baptistry, though there are no descriptions and not much is visible.
