Pietroasele is a commune in Buzău County, Muntenia, Romania, known for its vineyards. The name means "the rockies". The commune is composed of six villages: Câlțești, Clondiru de Sus, Dara, Pietroasa Mică, Pietroasele and Șarânga. It became famous with the discovery in 1837 of the Pietroasa Treasure composed of several pieces of gold and precious stones. The Romanian historian Alexandru Odobescu wrote a book on the archaeological discovery. The village is the centre of several archaeological sites such as the Dacian fortress at Dari Gruiu. The six locations that make up the commune were built after the sixteenth century, on the lands of freeholders and lords of the neighbouring village of Bădeni, and were later divided into three municipalities: Pietroasa de Jos, Pietroasa de Sus and Șarânga, which were merged in 1968. Although it was initially a centre for stone extraction, today viticulture is the main economic sector of the village, known for Romanian wine. The Viticulture Research Center found here is managed by the University of Agricultural Sciences in Bucharest. History A Dacian fortress is located at 1,5 km north of Pietroasa Mică village. Ruins of a third-fourth century AD Roman castra and thermae were discovered in the area in the 1980s. The Roman fort of Pietroasa de Jos, well beyond the Danubian Limes and near present-day Moldavia, would seem to have been occupied in the fourth century A.D. It was connected to bridge-head forts (Sucidava, castra of Tirighina-Bărboși, and the unlocated Constantiniana Daphne) along the left bank of the Danube river. Near this Roman fort, built by Constantine I when he created the Constantine Wall of the Limes Moesiae probably around 330 AD, researchers have found even a small thermae building in the 1980s. The Roman fortification (124 m x 158 m) was built in an area where was present the Culture of Pietroasa. The wall was 2.7 meters thick. Some stamped bricks of XI Claudia Pia Fidelis from Durostorum, specific to Traian ages, were discovered. Bricks stamps with LEG XI CL ANT and LEG XI CPF. Nowadays there is a small museum on the former site of the castrum. The nearly 4000 people living in Pietroasele live mainly of agriculture and farming, but a few are employed in tourism related to the Roman discoveries and museum. Petroassa treasure The Pietroasele treasure, an Ostrogothic hoard uncovered in 1837 by local villagers, is on display at the National Museum
