On June 2, 2020, the New York City Landmarks Preservation Commission reviewed proposals from Trinity Church and Murphy Burnham & Buttrick (MBB) Architects to replace its multi-story stained glass window located above the entrance with a commissioned stained glass window designed by British stained glass artist Thomas Denny. The proposal was approved.
In addition, Landmarks Preservation Commission (LPC) also granted Trinity Church necessary approvals to modify signage on the grounds of both the historic church and cemetery grounds. This includes digital displays, flagpole signage, and bronze placards.
