Nice open air museum to see. You can see hear the remnants of Galerius palace, basilica, cisterns, roman baths and hippodrome. There are mamy educational boards along the way in English and Greek.
To see and read all educational boards you need about 1,5 hour. In the ticket price you have also agora museum (you can visit it the next day as well on the same ticket).
To visit both sites (and reading all the educational boards in both places) we needed about 5 hours including a break in a café.
Unfortunately the mosaics are hidden under the cloth and dirt, maybe it will be shown in the future, when they will have enough budget to adjust it for tourists and prevent from being damaged. Also a nice mosaic with the dolphin, which you could have seen by the glass in the past is totally covered in bushes and you cannot see it at all now...
