The ruins of Nikopoli include scant Roman walls, better-preserved Byzantine walls and churches, and a theatre, all spread across a vast site. Stairs lead to the top of the Byzantine walls in some places (such as by Church B) but ascend these crumbling steps at your own risk. Allow an hour or two to hike the site, which is 6km from Preveza. Large stretches of the walls are parallel to major roads, so beware of traffic when crossing to admire temples and towers.
