Welcome to Old St. Mary's cemetery. I'm always a sucker for a cool cemetery so feel free to wander and explore.
But that's not why you're here. The coordinates will bring you to one of Dover's most interesting historical houses, The Round House. This unique home was originally a water tank built in the 1800s. There was a wealthy landowner, Johnathan Sawyer of Sawyer Mills fame. He had a 26 room mansion that stood where the decrepit former fast food joint now stands off of exit 7. The Round House supplied water for the mansion. The old home was razed in 1958 and the water tank was turned into a home in the 1970s. It supposedly has secret rooms and suits of armor inside- in addition to a granite shower made with a 300 pound chunk left over from the construction of the General Sullivan bridge.
Take the time to google "The Round House, Dover, New Hampshire" to see the stunning interior photos.
From the outside you can see the neat old brick structure, and the famous gargoyles that loom over the building. You are looking for a bison tube near the fence. The cache is located in the cemetery so please no night caching.
Congrats to pprn4fn for FTF!
