Does New Hampshire Have a Secret System of Tunnels?
For the past few months, New Hampshire has reportedly been hearing some odd booms in the middle of the night. While it’s possible they were a continuation of some of the strange earthquakes that hit Northern New England in 2022, there’s another theory that’s been quietly passed around by locals.
Could they be related to one of New Hampshire’s forgotten, underground tunnels?
In Lyman, New Hampshire, a former copper mine now serves as a crucial force in nurturing the state’s wildlife, according to Only In Your State. But before you go there looking to snap some candid photos of deer or rabbits, beware: the tunnel actually serves as a hub for bats.
Portsmouth’s secret tunnels are so impressive, one system even caught the attention of our enemies during the Cold War. Known as the Portsdown Tunnels, these passageways beneath the city first came into play during World War II, according to HampshireLive.com.
Though more famous for the strange things residents witnessed in the sky, Exeter is also famous for allegedly – and factually – having tunnels beneath the surface.
The Exeter News-Letter explored rumors of a tunnel in the basement of the Gilman Garrison House that some speculated was part of the Underground Railroad. However, beyond local hearsay, there apparently isn’t enough evidence of the corridor that was supposedly closed off to prevent children on the river’s edge from playing in it.
This is in contrast to tunnels that did and do exist beneath Philips Exeter Academy, and even served as a site used by instructors for a course activity, according to the school’s newspaper.
As for tunnels that are actually safe to visit? Look no further than Dover (which makes sense, as it was the birthplace of the Teenage Mutant Ninja Turtles). Several you may have never even noticed beneath the Spaulding Turnpike and Silver Street, according to one blog.
