Project Overview

  • Preserving the historic elements while making significant structural upgrades
  • Building was fully occupied throughout the phased duration
  • Extreme care of the irreplaceable stain glass windows

Built in 1872, the majestic church is located in the heart of downtown Cambridge and houses the City’s oldest congregation. Our in-house craftsmen self-performed comprehensive exterior masonry restoration and renovation work to the bell tower façade. The timber bell tower and louvers were structurally re-built, and a new roof was installed. We also restored and gilded the large ornamental weathervane and restored three 19th century, original Tiffany stained glass windows. Unique treasures, the hand made stained glass windows were painstakingly removed and transported to Williamstown, MA where they were restored and subsequently returned and reset in their permanent positions in the church sanctuary. Lastly, we refurbished the historic 19th century church altar. The limestone altar was dismantled, catalogued and restored, with all work being completed by our self-performance personnel.
