Hippodrome?

I found that some say that the Roman building mentioned in the previous post was a hippodrome. A hippodrome surely fits Aelia Capatolina, and the location would perhaps fit the teaser Hadrian. Yet, the building in the model seems different. If you know more, please leave a comment.

An Intriguing Model

I saw this intriguing model, carved out of rock, in a public place in the "Old City" of Yerushalayim. Towards the right, it shows how Hadrian restructured fort Antonia, nowadays known as the Temple Mount. To the left (South) of fort Antonia, an apparently Roman structure stands on the place of the Mikdash. The location of the model is just outside of fort Antonia, near its North-Western corner. Should someone have any knowledge about it or about the structure standing on Makom HaMikdash, please leave a comment.
