The Old Union Trust Building

Built in 1927–28 on the northeast corner of the New Haven Green, this was the city's tallest building when it opened, designed to echo the architecture of the Green's three historic churches. The Union Trust Company left in 1981; the building was converted to residences in 2014 and renamed "The Union." It has a long-standing local reputation, with reports numbering in the dozens over the decades: footsteps on empty stairways at night, banging on walls, orbs and unexplained images in photographs, lights and plumbing fixtures activating on their own, and voices calling out names with no one present. Local legend attributes the most persistent activity, centered in the basement, to a bank teller who died trapped in the vault after being caught embezzling — though that origin story is folklore rather than a documented record.
