No injuries were reported as crews in Chester contained flames and assessed the safety of the 19th-century structure.
CHESTER, Pa. — Firefighters in Chester battled a three-alarm fire early Wednesday at the former Immaculate Heart of Mary Roman Catholic Church on W. Second Street, attacking heavy flames from the exterior and closing nearby blocks while smoke drifted across the neighborhood.
The response began before sunrise and escalated as fire moved through the upper levels of the vacant, 151-year-old building. Dispatchers said the blaze reached a third alarm around 7 a.m., bringing more crews and tower ladders to the scene. Mayor Stefan Roots said the building has been empty for years and called the damage significant. The cause was not immediately known, and investigators planned to begin a formal origin-and-cause review once hotspots were cooled and the structure was safe to enter.
Crews were sent shortly after 5:40 a.m. to the 1400 block of W. Second Street near Upland Avenue, where witnesses reported flames showing from the roofline. Firefighters positioned aerial streams over the nave and operated from defensive positions due to collapse risks in the aging sanctuary. “Our first priority is life safety, then protecting our firefighters and surrounding properties,” an incident commander said at the scene. Police established a perimeter as neighbors watched from behind tape and morning traffic was rerouted off Second Street.
The church, built in the 1870s and closed in 1993, had long been a neighborhood landmark even in disuse. By daybreak, sections of the roof had burned through, exposing charred trusses. Utilities at the property were limited and routine occupancy was not reported. Firefighters cycled in fresh companies as the operation stretched through the morning. Water cascaded from the gables while ground teams chased embers in adjoining spaces and checked nearby buildings for heat damage. No civilian or firefighter injuries were immediately reported.
City and county investigators will document the scene, interview witnesses and review recent calls for service tied to the property. Officials said the fire marshal will examine where the roof failed and where fire advanced most quickly to narrow the area of origin. Engineers are expected to evaluate whether the remaining stone walls can stand safely. If instability is confirmed, emergency shoring or partial demolition could follow. An update is expected once investigators complete their initial walkthrough.
Neighbors recalled weddings, festivals and school events tied to the parish decades ago. “It’s a heartbreak for people who grew up here,” said Denise Alvarez, who drove over after seeing smoke from a mile away. A man who lives across the street said he woke to sirens and saw embers ride the wind over rooftops. By late morning, the air smelled of wet ash and hoses snaked across the block as crews shifted to overhaul and monitored for flare-ups.
As of Wednesday afternoon, the cause remained undetermined and access to W. Second Street was limited while firefighters checked for hidden fire in the rafters. Officials said additional information would be released after the initial structural assessment and investigative briefing.
