The Colonial City of Santo Domingo: Visitor and Heritage Guide

What was inscribed, and when

The Colonial City of Santo Domingo was inscribed on the World Heritage List in 1990. It is the Dominican Republic's only inscribed property, which is worth saying plainly: many guides to this region list three heritage sites per country because that is how the genre is usually structured. This country has one.

Why it matters

UNESCO's record is unusually blunt about the significance. After Columbus reached the island in 1492, Santo Domingo became the site of the first cathedral, hospital, customs house and university in the Americas. The town was founded in 1498.

The second half of the citation is the part that outlasted the buildings. The town was laid out on a grid pattern, and that plan became the model followed by almost every colonial town planner in the New World. When a city in Latin America has a central square with a church on one side and straight streets running off at right angles, this is where that came from.

⚠ What that history also is

The first of these institutions in the Americas were also the administrative apparatus of a colony. The same harbor and the same customs house that make the citation remarkable were the machinery of conquest and, shortly afterwards, of the transatlantic trade in enslaved people. Visiting the Colonial City means standing in both of those facts at once, and a guide that presents only the firsts is telling half of it.

What to see

• The Catedral Primada de America, begun in the 1510s, the first cathedral built in the Americas.
• The Alcazar de Colon, the house built for Columbus's son Diego, now a museum of the period.
• Calle las Damas, the oldest paved street in the Americas, and the simplest way to understand the scale of the original town.
• The Fortaleza Ozama, the fort above the river mouth that the city was built behind.
• The grid itself, which explains the place better than any single building: walk it rather than driving between monuments.

Visiting

• Go early. The Zona Colonial is hot by mid-morning and the light is better before it.
• Wear shoes with grip. The cobbles are uneven and slippery after rain.
• Churches expect covered shoulders and knees.
• It is a living neighborhood, not an open-air museum. People live on these streets.
• Ordinary city precautions apply: carry little, and use arranged transport after dark.
