You can see some of the conservation practices on my Ohrid and Heraclea pages. Here sand is placed over part of the mosaics as protection. I assume they rotate which sections are exposed.
I'm assuming these were for grain or for oil or ... there wasn't any information available that I could see. I would also assume that these are reproductions.
I *thought* I would remember what everything was -- anyway this is another Roman ruin at Stobi. From the looks I'd say it was a basilica.
The seats look as hard as your average college football stadium -- I wonder what the Romans brought to keep their seats comfy :)))))
These are the stairs you use to reach your seat in the amphitheatre -- I'd watch my step if I were you:) The amphitheatre at Stobi has not been renovated the way they have been at Ohrid and Heraclea.
Every Roman amphitheatre in Macedonia that can be used for performances is I think -- from Bitola, to Heraclea, to Ohrid to ... Stobi.
The baptistry forms a circle around what was the large baptismal font. The floor is covered with many animal and floral motifs as you can see in this photo.
