Warsaw prosecutor closes probe into fire of John Paul II's first mass cross, rules it accidental

A symbol of Polish faith

The wooden cross that burned in April 2026 stood outside the Church of St. Maksymilian Maria Kolbe on ul. Rzymowskiego in Warsaw's Mokotów district. It was not an ordinary religious monument. On June 2, 1979, Pope John Paul II celebrated his first mass on Polish soil after his election to the papacy at this very cross, then located at Victory Square (now Marshal Józef Piłsudski Square) in central Warsaw. In 1999, the cross was relocated to the Mokotów parish, where it became a focal point for local worshippers and a tangible link to the Polish pope's 1979 pilgrimage.

The April fire

The fire broke out on an unspecified day in April 2026. Emergency services began receiving calls at 15:23. Firefighters arrived within minutes and worked to extinguish the flames. After the fire was out, they dismantled the charred remains of the structure, completing their operations after 19:00. The fire did not spread to nearby bushes or church buildings. Investigators then entered the scene to collect evidence.

Investigation and findings

The Warsaw-Mokotów District Prosecutor's Office launched an investigation. On July 28, 2026, spokesman Piotr Antoni Skiba announced that the proceedings had been discontinued due to the absence of any criminal act. The investigation faced challenges: the site had no CCTV coverage, and no direct witnesses to the outbreak of the fire could be found. During the examination of the debris, investigators found numerous candles (both paraffin and battery-operated) and artificial flowers. No electrical installations or devices that could have started the fire were discovered, and there were no signs typical of arson, such as spilled flammable liquids.

During the procedural activities, the presence of numerous candles, both paraffin and battery-powered, and flowers was found. In the fire debris itself, no installations or devices whose operation could have initiated combustion were revealed, nor any traces typical of deliberate arson.

Chemical tests on samples from the fire site detected no flammable substances. A fire expert concluded that the only possible ignition sources were the candles placed at the base of the cross. The expert's report described two probable scenarios: either a candle's glass container cracked, releasing hot paraffin that ignited the wooden structure, or the candle flame first set fire to the artificial flowers, and the flames then spread to the dry boards of the cross. The boards were covered with trapezoidal sheet metal but had not been treated to be flame-retardant.

The thermal energy generated by the burning of artificial flowers or from the candle flame itself - in the expert's opinion - is sufficient to ignite dry boards covered with trapezoidal sheet metal, which were not treated to be flame-retardant.

The fire originated at the base of the cross on the right side and traveled upward through the hollow interior.

Aftermath and reconstruction

The discontinuation order is not final; the injured parties have the right to file an appeal with the court. The parish has already announced plans to rebuild the cross and restore it to its place in front of the church. The reconstruction will bring back a symbol that for over four decades has marked the memory of John Paul II's first mass as pope in his homeland.
