Considering the Le Mas de la Chapelle Hotel in Arles?

Le Theatre Antique by rwlittle
Near to the amphitheatre are the ruined remains of a Roman theatre. Over the years, the stones were quarried away to be used in other buildings, leaving mostly jumbled remains.
The photo shows one view of Le Theatre Antique, with myself standing in front of the "two widows" (the two standing columns remaining).
