In Brief
Center Church on the New Haven Green in Connecticut was built over the colonial burying ground in 1812 — not by moving the graves, but by raising the church on pillars and sealing the cemetery into the basement. The dead are still down there, intact, under the floor.
The Full Story
At the New Haven Green in New Haven, Connecticut, there's a church with a graveyard sealed inside its basement. Not a memorial, not a re-creation — the actual 17th- and 18th-century cemetery, left exactly where it was, with the church built on pillars over the top of it.
When the congregation put up Center Church in 1812, the colonial burying ground was already there underneath. Instead of clearing it, the builders raised the church on a foundation that arched over the graves and enclosed them. You can walk down into the room they made. Roughly 137 gravestones still stand in the dim, the oldest belonging to Sarah Rutherford Trowbridge, dated 1687. The church believes close to 1,000 people lie in that one chamber.
Some of the stones lie flat instead of standing — "wolf tables," they're called, laid horizontal over the graves. The story goes they were meant either to recreate the Last Supper or, more bluntly, to stop animals from digging the bodies up. Damned Connecticut describes them set out "in no particular pattern."
The floor is bare brick, and it's uncemented on purpose. In 1879 someone paved the dirt with concrete; by the 1980s the church found the slab was trapping moisture, turning the gravestones into wicks that drank the damp and crumbled. So in 1990 they tore the concrete out and laid loose brick instead. The room had to be able to breathe.
The Puritans who laid out the Green in 1638 sized it, as the legend has it, to hold the 144,000 souls they believed would be spared at the Second Coming. A square measured for the saved, with a roof now over the anonymous dead.
The hauntings here all happen above ground. In 1814 Yale's president Timothy Dwight wrote of a sixteen-year-old who, with a friend, tried to startle an apprentice crossing the Green at night — and lunged straight through him. The apprentice had died that day, and was already buried on the Green.
