5. Astor Place IRT Station
The terra cotta panels at the Astor Place IRT Subway Station are a small reminder of the wildlife that was once populated New York and much of the United States until the 19th century. The beaver is especially fitting in this station since John Jacob Astor, the station’s namesake, became the first American multi-millionaire from the beaver -pelt trade. While you are there, make sure to check out the station’s vintage subway entrance.
