The city plan for Athens underwent a major transformation in 1832 when Stamatios Kleanthis introduced wide avenues, public gardens, and grand buildings to the urban landscape. His design established the initial street naming convention for the city, marking a shift toward structured urban development before administrative budgetary constraints forced a simplification of the project.
Early Life and Military Service
Born in 1802 in Velventos, Kozani, Kleanthis relocated to Bucharest during his youth to attend the Greek School. His early adulthood was defined by the insurrection against the Turks in 1821. As a member of the Sacred Band, he served under Alexander Ypsilanti and participated in the Battle of Dragashani, where he was captured before managing an escape.

Following his military involvement, Kleanthis traveled to Vienna and then to Leipzig to pursue formal architecture training. He later completed his studies in Berlin under the tutelage of Karl Friedrich Schinkel. These formative years in Germany provided him with the technical foundation that would define his later work in Greece.
Public Works and Private Enterprise
Returning to Greece, he collaborated with Eduard Schaubert under the appointment of Ioannis Kapodistrias to serve as public engineers. Beyond his architectural career, Kleanthis became a successful entrepreneur. He managed marble quarries on the island of Paros, an enterprise that yielded significant wealth. His extracted marble earned a gold medal at the 1851 London Great Exhibition.
Architectural Legacy
Kleanthis designed notable structures including the Duchess of Plaisance’s mansion in Penteli, Rododafni Castle, and Villa Ilissia, which currently houses the Byzantine and Christian Museum of Athens. His personal residence in Plaka served as the initial site for the University of Athens and is now home to the Athens University Museum. He also designed the Memorial to the Fallen of the Sacred Band in Athens.
