Dacia was the land inhabited by the Dacians, its core in Transylvania, stretching to the Danube in the south, the Black Sea in the east, and the Tisza in the west. The Carpathian Mountains were located in the middle of Dacia. It thus roughly corresponds to present-day Romania, as well as parts of Moldova, Bulgaria, Serbia, Hungary, Slovakia, and Ukraine.
Romula or Malva was an ancient city in Roman Dacia, later the village of Reşca, Dobrosloveni Commune, Olt County, Romania. It was the capital of Dacia Malvensis, one of the three subdivisions of the province of Dacia.
Trajan's Wall is the name used for several linear earthen fortifications (valla) found across Eastern Europe, Moldova, Romania, and Ukraine. Contrary to the name and popular belief, the ramparts were not built by Romans during Trajan's reign, but during other imperial periods. Furthermore, the association with the Roman Emperor may be a recent scholarly invention, only entering the imagination of the locals with the national awakening of the 19th century. Medieval Moldavian documents referred to the earthworks as Troian, likely in reference to a mythological hero in the Romanian and Slavic folklore. The other major earthen fortification in Romania, Brazda lui Novac, is also named after a mythological hero.
Porolissum was an ancient Roman city in Dacia. Established as a military fort in 106 during Trajan's Dacian Wars, the city quickly grew through trade with the native Dacians and became the capital of the province Dacia Porolissensis in 124. The site is one of the largest and best-preserved archaeological sites in modern-day Romania. It is 8 km away from the modern city of Zalău, in Moigrad-Porolissum village, Mirsid Commune, Sălaj County.
The Moesian Limes is the modern term given to a linked series of Roman forts on the northern frontier of the Roman province of Moesia along the Danube between the Black Sea shore and Pannonia and dating from the 1st century AD. It was the eastern section of the so-called Danubian Limes and protected the Roman provinces of Upper and Lower Moesia south of the river. The eastern section is often called the limes Scythiae minoris as it was located in the late Roman province of Scythia Minor.
Athanaric's Wall, also called Lower Trajan's Wall or Southern Trajan's Wall, was a fortification line probably erected by Athanaric, between the banks of river Gerasius and the Danube to the land of Taifali. Most probably, Athanaric's Wall has reused the old Roman limes called Limes Transalutanus.
The Limes Alutanus was a fortified eastern border of the ancient Roman province of Dacia built by the Roman emperor Hadrian to stop invasions and raids from the east.
Brazda lui Novac is a Roman limes in present-day Romania, known also as Constantine's Wall. It is believed by some historians like Alexandru Madgearu to border Ripa Gothica.
