Fire is high on the list of threats to historic sites. All too frequently, horror stories of centuries-old buildings succumbing to flames make the news, and the public reacts with sadness at lost architectural treasures, as was the case when Notre Dame Cathedral in Paris caught fire in 2019. In November of 1872, Boston experienced tragedy as the largest fire in city history destroyed over 700 buildings. The fire was finally contained at the intersection of Washington and Milk Streets, mere blocks away from King’s Chapel. While this church remained unscathed, many neighboring historic sites burned, including Trinity Church, one of King’s Chapel’s daughter congregations. (The congregation of Trinity Church later moved from their Downtown Crossing location to a new building in Copley Square.) So it is extremely important for places like King’s Chapel to take every precaution available to protect their physical structures as well as all the people who visit.
Throughout its history, King’s Chapel has implemented systems and procedures to help protect against fires, updating them with technological advances. For instance, in 1852, the church installed its first official fire alarm system; it was connected to the city-wide electric telegraph system, the first of its kind in the United States. Boston’s telegraphic fire alarm system split the city into seven districts, each of which had multiple signal boxes. By turning a crank inside these signal boxes, witnesses could alert the superintendent of a nearby fire. This superintendent would then press a key for the corresponding district to set off a series of tolls from all the bells connected to the city-wide alarm system.
Thirty tolls notified firefighters of a fire and the subsequent number of tolls informed them of its location; for example two tolls would sound for a fire in district two. There was even a special signal to let firefighters know when a small fire was contained before their arrival. King’s Chapel was one of nearly sixty locations throughout Boston that was connected to the alarm and signal circuits of this system, stressing the importance of collaboration when dealing with fire prevention within a community.
In the early 20th century, King’s Chapel expanded its internal fire safety precautions to include a basic automatic sprinkler system, fire escapes, and eliminated use of the building’s coal boiler after a chimney fire. The sprinkler system was upgraded in 1940 to a more comprehensive alternative which included protection over the attic. This area saw further improvements in 1975, when a fire damper was added above the medallion which had once been a part of a cooling system. The basement sprinkler pipes were also inspected and rehung around this time. During church-wide renovations in 1991, the fire alarm system was updated and in the 21st century, King’s Chapel has continued to prioritize fire safety; today, there are pull stations, fire extinguishers, smoke detectors, and heat detectors in various locations throughout the building, as well as evacuation routes planned in case of emergency. With these ongoing improvements, King’s Chapel demonstrates its commitment to preemptive preservation, choosing to safeguard the building to the greatest possible extent.
