The Tropaeum Traiani is a monument in Roman Civitas Tropaensium (site of modern Adamclisi, Romania), built in 109 in then Moesia Inferior, to commemorate Roman Emperor Trajan's victory over the Dacians, in the winter of 101-102, in the Battle of Adamclisi. Before Trajan's construction, an altar existed there, on the walls of which were inscribed the names of the 3,000 legionaries and auxilia (servicemen) who had died "fighting for the Republic". (Latin: Tropaeum from Greek: Tropaion, source of English: "trophy").
Trajan's monument was inspired by the Augustus mausoleum, and was dedicated to the god Mars Ultor in AD 107/108 . On the monument there were 54 metopes depicting Roman legions fighting against enemies; most of these metopes are preserved in the museum nearby. The monument was supposed to be a warning to the tribes outside this newly conquered province.
By the 20th century, the monument was reduced to a mound of stone and mortar, with a large number of the original bas-reliefs scattered around. The present edifice is a reconstruction dating from 1977. The nearby museum contains many archaeological objects, including parts of the original Roman monument. Of the original 54 metopes, 48 are in the museum and 1 is in Istanbul.
The monument was dedicated with a large inscription to Mars Ultor (the avenger). The inscription has been preserved fragmentarily from two sides of the trophy hexagon, and has been reconstructed as follows:
NERVA[E] F(ILIUS) N[E]RVA
TRA]IANUS [AUG(USTUS) GERM(ANICUS)]
DAC]I[CU]S PONT(IFEX) MAX(IMUS)
TRIB(UNICIA) POTEST(ATE) XIII
IMP(ERATOR) VI CO(N)S(UL) V P(ater) P(atriae)
?VICTO EXERC]ITU D[ACORUM]
?---- ET SARMATA]RUM
The inscription, which calls Trajan Germanicus from previous his victories in Germany and Dacicus for his new conquest of Dacia, can be translated:
To Mars Ultor,
Caesar the emperor, son of the divine Nerva,
Nerva Trajan Augustus, Germanicus,
Dacicus, Pontifex Maximus,
Plebeian tribune for the 13th time,
[proclaimed] Emperor [by the army] for the 6th time,
Consul for the 5th time, Father the Fatherland,
Conquered the Dacian and the Sarmatian armies ...
On the monument was a frieze comprising 54 metopes. 48 metopes are hosted in the Adamclisi museum nearby, and one metope is hosted by Istanbul Archaeology Museum, the rest having been lost (There is a reference from Giurescu that two of them fell into Danube River during the transport to Bucharest).

In 1837, four Prussian officers, hired by the Ottoman Empire to study the Dobruja strategic situation, performed the first excavations. The team was composed by Heinrich Muhlbach, leading Friedrich Leopold Fischer, Carol Wincke-Olbendorf and Helmuth von Moltke the Elder. They tried to reach the center of the monument by digging an underground tunnel, nothing was found after the digging.
The monument was also visited by C. W. Wutzer from Bonn University, who recorded a short description of the monument and of some local legends.
The monument was researched by Grigore Tocilescu, O. Benford and G. Niemann, between 1882–1895, George Murnu in 1909, Vasile Parvan stop the researches in 1911, Paul Nicorescu studied the site between 1935–1945, Gheorghe Stefan and Ioan Barnea in 1945.
