Romula was once among the more important towns in Roman Dacia, and the ground at Reșca, in Olt county, is where it stood. The settlement grew near the river Olt on the road between the Danube frontier and the interior, and it rose to the rank of a colony in the later empire; the later name, Romula Malvensis, ties it to the province of Dacia Malvensis that was formed in the third century. Today you see fields, a few low mounds, and the faint outline of an old fortification, with finds from the site kept in nearby museums rather than at the roadside.
That makes the visit more about imagination than spectacle, which suits some riders and frustrates others. What the place does give you is context: you can see why a city grew here, on the flat open ground near a river crossing and a major road, and you can understand how a province built on military roads still had to feed, house and entertain its people. Stone from the city was reused over centuries by villagers building farms, which is one reason so little stands above ground.
The riding around Reșca is in the same spirit, flat and straightforward, with long straights between villages and the occasional bend around a farmyard. The surfaces vary widely, so ride the last kilometres with respect for potholes and tractor mud, and watch for dogs and carts. Summer is hot with little shade, and the best time is spring, when the fields are green, or early autumn, when the light turns amber over the stubble. The wind off the plain can be strong enough to push a lightly loaded bike sideways, which is worth knowing before you set off.
For practicalities, Fărcașele, about four kilometres away, is the nearest settlement of any size, and Dobrosloveni is also close, with its own shops and a small-town character; both are big enough to have a pump or a shop for a drink and a snack. If you need a wider choice, the bigger towns along the Olt valley have supermarkets and restaurants. Bring water in July and August, because a Roman ruin in a field has no café. Spend half an hour walking the ground and reading what you can, and let the quiet do the rest.
