This route is about 3 km, about 80 minutes and of moderate difficulty. It starts from Antikas Square and ends at the border of the old town with the modern city to the west. Through this route, the visitor has the opportunity to get to know the practice of neoclassicism and eclecticism, as expressed in about 50 buildings of old Xanthi.

Neoclassicism appeared in the 18th and 19th centuries and is strongly influenced by the principles governing the architecture of classical antiquity. The buildings are distinguished for the simplicity of their geometric forms, the Doric detail, the simplicity, the absolute symmetry, the dividing lines of the vertical spreads and the pilasters with false capitals at the corners.

Eclecticism, on the other hand, is the architectural style of the 19th and 20th centuries, in which a variety of elements from various eras and styles are selected and used, in a single building. The eclectic buildings in Xanthi are influenced by neoclassicism (e.g. absolute symmetry, verticality), while individual elements are influenced by Art Deco (e.g. strong decorative mood), central Europe (e.g. turret roof configuration or turret development), English Baroque (e.g. the use of red brick) and Romanesque style (e.g. arched openings and curved arches).
