Bonus#3 Remnants of the Old (Now Covered) Reservoir
Before Olmstead and Vaux got their hands on the Central Park site, a rectangular reservoir had been built in 1842. According to the Times, they felt “cursed” by the gawky thing and designed around it. It was filled in and covered in the 1930s but you can see elements when you walk by the 86th Street police station inside the park. You can even see the rock wall inside the new police station’s conference room. There’s also a historic marker near the Shakespeare theater.
