The Tower of Orestes, a primary feature of the site, is named after the Byzantine official Orestes who oversaw its renovation in the 14th century.
The masonry incorporates repurposed Roman architectural elements, a common practice in Byzantine defensive construction.
The site provided refuge for the local population during the various raids on the Serres region throughout the 13th and 14th centuries.
Archaeological excavations have uncovered evidence of multi-layered fortifications dating back to the Hellenistic period, later utilized by the Byzantines.
The hilltop location was strategically chosen to control the mountain pass leading toward the Bulgarian border.
The Byzantine Acropolis of Serres, locally known as Koulas, sits atop the hill of Agios Ioannis overlooking the city. It features substantial remnants of Byzantine fortification walls and the notable Tower of Orestes. The site functioned as a defensive stronghold during the Byzantine Empire to monitor the Strymon River plain. The northern section of the wall retains sections of brick and stone masonry characteristic of the period. Ongoing archaeological efforts have focused on stabilizing the medieval masonry. The hilltop position provides a 360-degree vantage point of the surrounding Serres valley and nearby mountains.
