Ciudad Colonial is the historic central neighborhood of the Dominican Republic's capital Santo Domingo. It is the oldest continuously inhabited European-established settlement in the Americas. The area has been declared a World Heritage Site by UNESCO. It is also known as Zona Colonial or more colloquially as "La Zona".
The Ciudad Colonial is located on the west bank of the Ozama River, which bisects the city. It covers 1.06 km² bounded by a walled perimeter. It is an important section of the city due to the high number of landmarks, including Alcázar de Colón, Fortaleza Ozama, Catedral de Santa María la Menor, and others. The area is the main tourist attraction of Santo Domingo, even though the main sites of governmental and commercial activity are now in the more modern parts of the city.
