History: The city grew up around the Hotel del Coronado, which opened in February 1888, less than three years after developers bought the land. Well-heeled visitors flocked to the hotel, and those with less means took up residence in Tent City, a makeshift summer community that operated from 1900 to 1939. Coronado is also known as a Navy town with the adjacent North Island Naval Air Station. It was here that aviation pioneer Glenn Curtiss experimented with seaplanes and opened a flight school for the U.S. military, earning North Island the title of “Birthplace of Naval Aviation.”
