The amphitheatre of Rusellae

The south pedestrian entrance with a line of sight across the minor axis of the amphitheatre to the north entrance.

The north entrance from inside the amphitheatre. No superstructure survives, and it doesn't look like there were any outside stairs up to entrances on the spectator level (as in the amphitheatre at Pompeii); since there is no cavea (the complex basements as in the Colosseum in Rome), apparently people walked in onto the field then up to their seats. Then the performers must have come in from the outside, probably via the main entrance, below. There must surely have been wooden gates in the pedestrian entrances to allow people to enter and leave during the show. I would not like to share the floor of an arena with a tiger.

This was the main entrance on the west, and the only one set up for vehicles; notice the threshold.

View of the amphitheatre from just above the main entrance. Clearly visible on the left, as well as in the next image, good examples of "opus reticulatum": literally, "net-work", from the attractive gridlike pattern of the stones, which are placed edgewise for greater solidity.

According to the careful written explanations provided at the site by the Soprintendenza (an attractive, unobtrusive and useful signposting system, by the way), no one knows what this structure was for. This one is in the northeast corner of the field, and there is another in the northwest corner. To me, it looks like a concession stand: a thermopolium, to give it its Latin name.
