History:
<p>The inscription on the attic records the foundation of the colony on the part of Trajan in the year 100. The decorative fabric of the monument, with the sides of the lateral arches detached from the wall, was taken with a curvilinear pediment that forms two protruding and strongly contrasted lateral aediculae. This and the lavish decoration of the architectural elements, all suggest a later dating.[1]
</p>
The arch together with the whole archaeological site of Timgad, has been listed as a World Heritage Site by UNESCO since 1982.
