Santo Domingo packs the New World's oldest colonial core into a single walkable district, making the Zona Colonial the natural focus of a short stay. Within it, the Columbus Palace stands as the oldest viceregal residence in the Americas, while the neighboring Cathedral of Santa María la Menor claims the title of the continent's first cathedral. Rounding out the historic core, the Museum of Royal Houses traces four centuries of colonial governance through original artifacts. A guided Colonial District Walking Tour ties these sites together efficiently, and if time allows, Juan Dolio Beach offers an easy coastal escape without straying far from the capital.
