The Tropaeum Traiani or Trajan's Trophy lies 1.4 km northeast of the Roman city of Civitas Tropaensium. It was built in AD 109 in then Moesia Inferior, to commemorate Roman Emperor Trajan's victory over the Dacians in 106, including the victory at the Battle of Adamclisi nearby in 102.
It was part of a monumental complex comprising the trophy monument, the tumulus grave behind it and the commemorative altar, raised in 102 AD for soldiers fallen in the battles of this region. The complex forms a triangular plan, the base being marked by the monument and the funerary tumulus while the upper point is the altar.
