Did You Know?

The Oldest European City in the Americas

Santo Domingo was founded in 1496 and holds the first cathedral, first university and first hospital built in the Americas. Its colonial quarter is a UNESCO site and still the city's living centre.

The clock: the Dominican Republic keeps UTC−4 year-round. It shares Hispaniola with Haiti, which observes daylight saving — so for part of the year the island runs on two clocks.
