Modern Béja sits directly on top of ancient Vaga, and as a result the Roman city itself is largely invisible — its stones long since reused in the kasbah, the mosques, and the medina houses. What remains is scattered: occasional carved stones built into walls, fragments of columns set up as ornaments, and an inscription or two visible to those who know where to look. The town is a study in how Roman North Africa survived not as ruins but as building material.
A small archaeological collection in the town displays what has been recovered locally — mosaics, statuary fragments, oil lamps — and helps put the surrounding countryside into context. If you are headed onward to Bulla Regia or Dougga, a stop here gives a sense of how dense Roman settlement was across this entire region: every town was once another Vaga.
