Why It Feels Like Lisbon
Old San Juan’s pastel‑colored, tile‑roofed buildings and narrow cobblestone callejones mirror Lisbon’s Alfama district, while the sea‑borne breezes and hilltop forts evoke the city’s iconic miradouros. The vibrant plazas, such as Plaza de Armas, pulse with fado‑like guitar street performances, and the historic forts provide a maritime grandeur reminiscent of Belém. The blend of Caribbean flair with European stonework creates a unique colonial‑European hybrid.
