Read the full account

Romanian and UNESCO-adjacent publication of Sarmizegetusa Regia’s wider landscape and of Ulpia Traiana prints a Trajanic colonial city. Urban implantation is both displacement (other row) and a built public grid.

Context

Trajan Shared work with other named actors remains in the record.

Trajan’s documented role is bounded by other offices and collaborators named in the sources below.

Conventional reign is 98–117 CE.
