Walk into any large square in Naples, Italy, and the city's history comes into focus. Arched galleries, sweeping colonnades and domes that echo ancient architecture compete for your attention. Every street shifts in style—compact Baroque facades give way to broad Neoclassical courtyards. Continue exploring, and you will arrive at a wide square with a building that appears Roman at first sight. That's the Basilica of San Francesco di Paola, located on the west side of Piazza del Plebiscito.

Completed in 1846, the basilica took shape after Ferdinand I, King of the Two Sicilies, returned to power and continued the construction begun under King Joachim Murat of Naples. The design followed strict Neoclassical principles: a circular body, a triangular pediment and a dome modelled after the Pantheon—a famous second-century Roman temple.

Inside, the geometry continues with polished marble, broad arches and chapels spaced along the circular walkway. The piazza features a curving colonnade that borders the basilica and frames its dome. Planning a trip to Naples? Piazza del Plebiscito awaits you.
