Pest House
Lebanon, Grafton County, New Hampshire
Marker Inscription
While many may not know there is a lot of mystery to the Cellar Hole in front of you. It is known to many historians of Lebanon that there was a Consumption House or "Pest" House established to inoculate those affected with smallpox sometime in the 1790s.
The Story
The cellar hole here marks the site of a 1790s "pest house," a building set apart to inoculate and isolate people during smallpox outbreaks. In the years before vaccination became widespread, New England towns commonly built such houses on their outskirts to contain the deadly, contagious disease. Little remains today but the foundation and the memory kept alive by local historians.
Why it matters
It recalls an early American answer to epidemic disease — quarantine and inoculation — at the very dawn of the medical breakthroughs that would eventually conquer smallpox.
The story behind this marker
AI contextThe era
In the 1790s, the young United States was still very much a rural, small-town nation, and few things frightened those towns more than smallpox. The disease swept through communities in waves, killing a significant share of those it infected and leaving many survivors scarred or blinded. In an age before modern medicine understood germs, an outbreak could empty a village of its confidence overnight.
New England towns like Lebanon, in the hill country of New Hampshire, met that terror with the tools they had: separation and early, deliberate exposure. The standard defense was to set the sick — and those undergoing treatment — apart from everyone else, often in a building deliberately placed at the edge of the settled area.
This was the Early Republic, a time when public health was a local, hands-on affair decided by town meetings and neighbors rather than distant agencies. A community that wanted to protect itself had to organize its own answer, brick by brick and rule by rule, and the "pest house" was one common form that answer took.
People & events
The cellar hole here is what remains of one such building — remembered by local historians as a "pest" or consumption house established in the 1790s to inoculate people against smallpox. The very name carried a warning; a "pest house" was where contagion was kept at arm's length from the healthy town.
The practice it served was inoculation, an older forerunner of vaccination. In this method, a person was deliberately given a controlled case of smallpox in hopes of producing a milder illness and lifelong immunity. It was risky and frightening work — the inoculated could still fall gravely ill, and could spread the disease — which is exactly why it was carried out in an isolated house set apart from everyone else.
Much about this particular site remains, by the marker's own admission, a matter of mystery and local memory rather than a fully documented record. What survives is the knowledge that people came to this spot to face one of the era's deadliest diseases head-on, and the foundation they left behind in the ground.
Its place in the American story
The pest house sits at a hinge point in the long human struggle against epidemic disease. Inoculation was the imperfect, brave bridge between simply enduring smallpox and finally defeating it. Within a few years of this house's era, a safer method using cowpox — vaccination — would begin to spread, and over the following generations it would drive smallpox back until the disease was ultimately wiped from the Earth.
A humble cellar hole in New Hampshire is a small monument to the start of that arc. It shows the earliest American public-health instincts already at work: isolate the contagious, protect the community, and take a calculated risk to build immunity — the same basic logic that underlies disease control to this day.
It's also a reminder of how local this fight once was. There was no national program to lean on; a single town, worried for its families, built its own answer at its own outskirts. Multiply this one site across hundreds of communities and you have the grassroots foundation on which modern public health was eventually built.
If you visit
What you'll find here is a cellar hole — a stone-lined foundation set into the ground, with the woods and fields of Lebanon around it. There is no grand structure to tour; the reward is atmospheric and imaginative, the sense of standing where something quietly important once happened.
Give yourself over to the mystery the marker itself embraces. Picture a plain building set deliberately apart from the town, and the mix of fear and hope that must have hung over anyone who walked toward it seeking protection from a killer disease.
This is a stop for travelers who like their history contemplative and a little haunting. Tread respectfully, resist climbing on the old stonework, and let the emptiness of the site do its work — sometimes a foundation and a good story are enough to make the past feel very close.

BASIC: The First User-Friendly Computer Programming Language
Hanover, NH
In 1964, Dartmouth mathematicians John Kemeny and Thomas Kurtz set out to make computing something ordinary students could do, not just specialists. Their language, BASIC — Beginner's All-purpose Symbolic Instruction Code — used plain, English-like commands and ran on Dartmouth's pioneering time-sharing system, letting many users share one computer at once. As inexpensive personal computers spread in the 1970s and 1980s, BASIC became the language millions of people first learned to program in.
Cannon Mountain Aerial Tramway Cabin
Lincoln, NH
This tramcar once climbed Cannon Mountain in New Hampshire's Franconia Notch as part of the first passenger-carrying aerial tramway in North America, opened in 1938. Loaded, it lifted more than two dozen riders to the summit in about nine minutes, opening the high country to sightseers and skiers in a way no road or trail could. This car did the work for more than four decades before being retired and preserved.
Swasey Parkway — Gift of Ambrose Swasey
Exeter, NH
This riverside parkway along the Squamscott River was a 1931 gift to the town of Exeter from Ambrose Swasey, a New Hampshire-born mechanical engineer and industrialist who rose from a Northfield farm to co-found the Warner & Swasey Company of Cleveland. That firm became famous for precision machine tools and for building some of the era's great astronomical telescopes, and Swasey channeled the fortune he earned into philanthropy for his native state. In dedicating the parkway he gave Exeter a lasting stretch of public green space where the town could gather along the water.
Swasey Parkway
Exeter, NH
Swasey Parkway runs along the tidal Squamscott River in Exeter, the gift of native son Ambrose Swasey, an inventor and machine-tool maker who was born here in 1846 before making his fortune building precision instruments and astronomical telescope mounts. Dedicated in 1930, the riverside promenade was his way of giving something lasting back to the New Hampshire town of his childhood. More than ninety years on, it endures as a green civic space where residents still stroll, gather, and watch the river slip past.
