Capitolium of Constantinople

[1] However, this position is refuted by De Ceremoniis, a 10th-century Byzantine ceremonial handbook, which mentions it as a landmark along the Emperor's triumphal procession.

[3] The building, together with the circus, the Great Palace, the Strategion and the Forum of Constantine, was one of those edifices needed to introduce the city as the new Rome.

[4] The edifice was originally a capitolium, that is a pagan temple dedicated to the Capitoline Triad, but in the early fifth century a cross had already been put on its roof, although a conversion to church is not attested.

[4] At the latest in 425 AD the Capitolium was turned into an academy of higher education, the Pandidakterion, hosting public lessons at the southern exedrae.

[4] The Capitolium had also exedrae along its eastern and western sides, but these did not border any road, and until 425 were occupied by popinae ("wine bars" in the Roman world).
