In 1493, Columbus found, when he returned in his second trip, that "La Navidad" was destroyed by the Indians and all Spaniards killed. Then he went to the east, founding the first European city in the American continent, near the present city of Puerto Plata; he named the city "La Isabela" in honor of Queen Isabella of Castile. The first Catholic mass in America was celebrated at La Isabela on January 6, 1494. From La Isabela, Columbus sent groups of persons to explore and take control of the island.
