Building of the Regional Unit of Serres (Dioikitirio)

The Building of the Regional Unit of Serres (known as the "Dioikitirio") is an impressive neoclassical structure, built between 1892 and 1898, most likely based on designs by architect Xenophon Paionidis.

It was erected during the Ottoman reform period (Tanzimat), reflecting the growing administrative demands of the era due to the expansion of the railway network. Initially serving as an administrative center for the Ottoman authorities, the building came under Greek control after the liberation of Serres in 1913, subsequently housing the Prefecture and today the Regional Unit of Serres.

Designed in an inverted “Π” (pi) layout, the building incorporates elements of neoclassicism and eclecticism. Its architectural form exudes a European aesthetic and conveys the authority of the state. Despite the destruction of the First Balkan War, the structure survived and remains one of the few preserved buildings of that era. Today, it continues to serve as a governmental hub, is well maintained, and has hosted notable cultural events such as light festivals and digital projections.
