We visited this former tentative site on the drive from Bath to Blaenavon. It is a nice visit with the totally overgrown amphitheater, the outlines of a legionary fortress and parts of a once large bath area. roman remains of those dimensions can be found all over Europe in probably dozens of places (including the more impressive Augusta Raurica in Switzerland). The Roman Legion Museum seems great for kids. Considering the many and much more impressive Roman WHS this site seems too modest to ever have a chance.
