Trinity Church is a National Historic Landmark considered by architects to be one of the top ten most important buildings in the country. Over the course of four years, from 2002 to 2006, the building was restored and expanded within the tight confines of Boston’s bustling Copley Square. The building remained open and operational while installing an environmentally-friendly geothermal heating and cooling system, expanding the Undercroft to provide 13,000 square feet of new program space, and restoring the exterior stones and mortar of the Central Tower to their original color scheme, which included a “Richardson red” mortar. The renovation and restoration of Trinity continues in phases.

•    February 2002
The Alliance supported Trinity’s efforts to secure a project grant from the Cynthia Woods Mitchell Fund of the National Trust for Historic Preservation.
