The colonial part has been carefully restored to retain its original charm, and is home to the first university, cathedral and hospital built in the New World. The modern city of Santo Domingo, by contrast, is a thriving port city, equipped with discos, gambling casinos, shops and the Cultural Plaza , which houses the Gallery of Modern Art and the National Theater. Just a few miles east of the city is a remarkable cave complex, Los Tres Ojos de Agua (The Three Eyes of Water), so-called because it contains three turquoise lagoons on three different levels, each fed by an underground river and surrounded by countless stalactites, stalagmites and lush tropical vegetation.
