Fiorentino
Fiorentino hosts San Marino's Olympic Stadium—the micro-state has competed in every Olympics since 1960 without winning a medal.
Fiorentino occupies San Marino's southern territory, its name suggesting Florentine influence during medieval Italian city-state competition. The castello hosts the republic's sporting facilities including the Olympic Stadium—unusual infrastructure for a micro-state of 33,000 people, but consistent with San Marino's strategy of international visibility through Olympic participation and FIFA membership. The republic has competed in every Olympic Games since 1960 despite never winning a medal, demonstrating how small states use sport for sovereignty signaling. Fiorentino's industrial zone contributes to the manufacturing sector that replaced banking after the 2008 financial crisis exposed San Marino's vulnerability to tax haven reputation damage. The castello's growth reflects population redistribution from crowded historic center to peripheral development. By 2026, EU integration may accelerate industrial development in accessible southern castelli while historic tourism concentrates on Mount Titano's peaks.
