Santo Domingo (est. 1496)
Ciudad Colonial (Spanish for "Colonial City") is the first settlement made by Christopher Columbus and the Spanish explorers in the New World. It has been declared a World Heritage Site by UNESCO. Colloquially known as "Zona Colonial" (Colonial Zone), Ciudad Colonial is part of the original Santo Domingo, Dominican Republic, and the origin of the district dates back to the 1500s. The Spanish used this settlement as the first point of influence in the Americas, from which they conquered much of the American mainland. Even though Spaniards focused their attention more on the mainland after conquering Mexico, Peru, and other regions of Latin America, Ciudad Colonial remained an important historical site.
The city was surrounded by a defense wall extending from the Ozama River to "La Puerta del Conde" ("The Gate of the Count", in Spanish), which was the only entrance to the hinterland and the furthest boundary of the city until around the late 19th century.
There's a street called "Calle Las Damas" considered the first street ever made in the Americas. You can truly feel in peace in this place, and feel as if you are back into the past. I suggest you visit.
