I believe they will restore the small domed mausoleum (K3) next to the Gymnasium. You can see its conical roof partially assembled above. As for excavations, the city is very large and most of it is still under the olive trees
In any case, the site's main goal is to finish the UNESCO world heritage site admission.
Ολοκληρώθηκε η εγκατάσταση και ξεκίνησε η λειτουργία του νέου συστήματος ηλεκτρονικού εισιτηρίου (e-Ticketing) και ελέγχου πρόσβασης επισκεπτών (access control) στους προβλεπόμενους αρχαιολογικούς χώρους και μουσεία της αρχικής φάσης του έργου (Ακρόπολη και αρχαιολογικοί χώροι του ιστορικού κέντρου της Αθήνας, Κνωσός και Αρχαιολογικό Μουσείο Ηρακλείου, αρχαιολογικός χώρος και μουσείο Αρχαίας Μεσσήνης).
Serapis and Isis in ancient Messene
The exhibition refers to the newly discovered great sanctuary of goddess Isis and god Serapis at the archaeological site of the Ancient Messene, which has partially come to light immediately south of the Theatre, exactly where Pausanias saw it in the 2nd century AD.

I have to admit that Mr Themelis is not only capable and hard working but also an insightful man. I hope his co-workers will follow his approach on excavations and restorations.
