2. The Survey Bolt

The bolt in this Central Park rock is believed to be one of the original survey bolts from when the city grid was first planned in 1811. Led by John Randel, surveyors had the task of marking each future street intersection aligned with the grid. They used marble monuments or iron bolts where there was exposed bedrock. The bolts bore a cross across the top.

Very few of these markers exist anymore. Most were removed as roads and intersections were built. However, Central Park was not a part of the original plan for the city, known as The Commissioners’ Plan of 1811. so street intersection points may have been marked according to the grid, and left to remain since no intersection was actually built here.

This bolt is known to be in the park, but the exact location is kept a secret for fear that it will be stolen or destroyed. After some intense searching of both the internet and park, you might be able to find it like I did.

Where to find it: We aren’t telling! (…And we request that our readers refrain from doing so in the comments.)

  1. For those living in the Upper East Side , nothing is prettier than exploring Central Park in the springtime. After all that walking around, check out some of the neat eateries that pop up. I recommend the Rogue Tomate’s Cart in the Park. You can end the day with an upscale picnic by the zoo!

  2. Is there an good walking tour book for central park you can reccommend
