Slăveni is farm country, and the fort here is the sort of ruin you have to meet halfway. "La Cetate" simply means "at the fortress", the name locals gave to a rise in the fields long before anyone excavated it, and what remains of the Roman auxiliary fort is mostly a matter of banks, ditches and the shape of the ground rather than standing walls. If you expect a Hadrian's Wall photograph you will be disappointed; if you like imagining a few hundred soldiers watching a very flat horizon, you will be fine.
The setting explains the fort. This is the Oltenian plain in the south of Romania, a few dozen kilometres north of the Danube, where the Roman province of Dacia needed garrisons along its roads and river lines. Corabia, on the Danube, was the Roman town of Sucidava, and the ride's other stops hang off that old military geography. Soldiers moved up through country like this from the river toward the Olt, and the forts were placed a day's march apart, so the logic of the route is still readable on a map even when the ground is quiet.
For a rider, the interest is the approach rather than the destination. The local roads are straight and agricultural, lined with maize, sunflowers and wheat depending on the month, with the occasional horse cart and a lot of dogs that have opinions about motorcycles. Surfaces vary from decent asphalt to patched and potholed, and the verges can carry mud or straw after harvest, so keep your speed honest at the edges of villages. Summer is hot and dusty with little shade; late spring and September are kinder, and the light on the stubble fields in the evening is worth the detour.
Practicalities are simple. Slăveni and Gostavățu are small villages with a shop or two, but for fuel and a proper meal head for Drăgănești-Olt, about eleven kilometres away, which is large enough to have pumps and somewhere to sit down. Carry water in the warm months, because between the villages there is nothing at all. Take ten minutes to walk the rise, read the sign if there is one, and then get on with the day. Nobody comes here for the corners, but you will remember it as the place where the map of an empire became suddenly physical under your boots.
