The North Theatre, built in 164 or 165 as a bouleuterion, a place of assembly for the representatives of local tribes who could vote. In the first quarter of the third century it was instead used as an odeon. To the originally 800 seats another 800 were added, building an extra 8 rows, a feat of architecture which explains the pronounced divide between the two groups of seats. In front of the theatre ran the North Decumanus, at the spot where the theatre stand an impressive flight of stairs leads up to it.

This is one of two shots that rather show the buildings in front of the theatre, which is to the right. On a map it is indicated as "Square in front of the theatre". Compare this to the pictures at the end of this group, taken at ground level.
