Pietroasele Roman Fort

Pietroasele Roman Fort – A Late-Roman Stronghold in the Heart of the Romanian Plain

Perched on a gentle plateau 25 km northwest of Buzău, the Pietroasele Roman Fort is the only late-Roman fortification in the Romanian Plain, constructed between 324 and 328/330 AD under Emperor Constantine the Great. Part of a defensive system designed to monitor and block the corridor between the Curvature Carpathians and the Danube in Dobruja, the fort reinforced the north-Danubian territories reclaimed from the Goths. Covering an area of 124 x 158 meters, the fort lies over 100 km from the Danube, marking a strategic Roman presence in the region.

Architecture and Archaeological Remains

The fortification is surrounded by a necropolis where coins minted during the reign of Constantine II were discovered. Adjacent to the site, fragments of Roman tiles were identified, forming part of the fort’s and civilian settlement’s water supply network. An ingenious system of water conduction and distribution, carved directly into stone, highlights the advanced organization of the garrison. Among the recovered archaeological materials are ten fragments of bricks and tiles bearing the insignia of the Legio XI Claudia Pia Fidelis, suggesting the presence of subunits of this legion, relocated from Durostorum (modern-day Silistra).

Just 400 meters east of the fort, a building with a hypocaust—unique in Romanian territory—housed the garrison commander’s residence, a high-ranking figure in the Roman military hierarchy. Constructed using the same techniques and materials as the fort, the building featured large basins for troop hygiene, spaces for thermal treatments, military meeting rooms, and chambers for reading, music, or exercises. The central heating system, with heat circulating beneath floors and through walls, alongside wastewater drainage channels, reflects the sophistication of late-Roman engineering.

Access and Visitor Recommendations

The Pietroasele Roman Fort is accessible via county road DJ203K, connecting Buzău to the village of Pietroasele. Visitors can explore the open-air archaeological site, and nearby, at the "Grădina Crudului" (1 km northwest), lies the discovery site of the famous 1837 "Hen with Golden Chicks" Treasure. While there is no dedicated museum on-site, the open-air ruins and historical context offer an authentic journey into the late-Roman era, complemented by the hypocaust building, accessible during guided tours periodically organized by the Buzău County Museum.
