Santo Domingo's Ciudad Colonial, which translates from Spanish as "Colonial City," is the oldest continuously inhabited European settlement in the Americas. This area that is surrounded by a walled perimeter and spans 1.06 kilometers is a World Heritage Site as recognized by UNESCO. It is the most popular tourist destination in Santo Domingo, and is home to numerous landmarks such as Alcázar de Colón, Fortaleza Ozama, and Catedral de Santa María la Menor. Despite the fact that most of the city's governmental and commercial activity is based in more modern parts of the city, Ciudad Colonial is still a major attraction.
