context_page_description: Trajan's Forum was the last of the Imperial fora to be constructed in ancient Rome. The architect Apollodorus of Damascus oversaw its construction.
context_section_description: The Forum consisted of a sequence of open and enclosed spaces, beginning with the vast portico-lined piazza measuring 300 metres (980 feet) long and 185 metres (607 feet) wide, with exedrae on two sides. The main entrance was at the south end of the piazza, through a triumphal arch at the center commemorating the Dacian Wars, decorated with friezes and statues of Dacian prisoners. The arch was flanked by tall walls built from blocks of Peperino tuff clad entirely in marble, which enclosed the Forum on three sides.
  The tuff walls which enclosed the piazza to the west and east featured exedrae; outside the exedrae, separated by streets, were markets of concentric shape. The three-story eastern market, known as Trajan's Market, buttressed the excavated edge of the Quirinal Hill. The open space of the Forum measured about 300 feet by 380 feet, and was paved entirely in Carrara marble. Via a doorway in the far east wall of the Forum, one gained entry to an open courtyard with a portico, which communicated in turn with the neighboring Forum of Augustus. 
  Along the piazza's north side was the Basilica Ulpia, and north of that was a smaller piazza, with a temple dedicated to the deified Trajan on the far north side facing inwards. The position of – and very existence of – the temple dedicated to the deified Trajan is a matter of hotly contested debate among archaeologists, particularly clear in the ongoing debate between James E. Packer and Roberto Meneghini. Between the Basilica Ulpia and the terminal piazza containing the temple, were two libraries, one housing Latin documents and the other Greek documents.  Between the libraries stood the 38-metre (125-foot) Trajan's Column. The libraries housed state archives including the acts of the Emperors and the edicts of the praetors.
  Trajan's successor Hadrian added a philosophical school adjacent to the piazza containing the Temple of Trajan. The building consisted of three parallel halls separated by annexes and was known as the Athenaeum; it functioned variously as school, a venue for judicial proceedings, and an occasional meeting-place for the Senate. 
  Constantius II, while visiting Rome in the year 357, was amazed by the huge equestrian statue of Trajan and by the surrounding buildings:
  But when he [Constantius II] came to the Forum of Trajan, a construction unique under the heavens, as we believe, and admirable even in the unanimous opinion of the gods, he stood fast in amazement, turning his attention to the gigantic complex about him, beggaring description and never again to be imitated by mortal men. So renouncing all hope of attempting anything of the kind, he said he wanted to imitate only Trajan's horse, set in the middle of the atrium, and with the emperor on its back. And prince Ormisda ... standing beside him, replied with pleasing wit: "First, emperor, command the construction of a stable like this, so that the horse you wish to have made can find as appropriate a setting as that we have before our eyes."
  — Ammianus Marcellinus, Histories XVI.10.15-16
