Steve Tobin’s The Trinity Root was made to commemorate a sycamore tree in the churchyard of Trinity’s St. Paul’s Chapel that took the brunt of debris from the Twin Towers (which were across the street) and saved the historic chapel from serious damage. He gave it to Trinity for free in exchange for the promise that the church would keep it in its courtyard permanently. Then, two years ago, a new rector packed the sculpture off to Connecticut.
