Hoboken, New Jersey
In 1832, a cave called Sybil's Cave opened and was popular. At that time, Hoboken was not yet an industrial city, and Hoboken was a country spot. Sybil's Cave was used in one of Edgar Allan Poe's stories in 1841. The water in the cave was bad, so the cave closed in the 1880s. In the 1930s it was filled with stone but in 2005 it was reopened.
