In the afternoon of Sunday, October 22, a wall from a historic construction in downtown São Luís collapsed following a rapid rainstorm with wind. The incident occurred on Rua Coelho Neto, adjacent to Praça Maria Aragão, but fortunately, no injuries were reported. Witnesses noted that the wall, approximately six meters in height, fell across the street, damaging a nearby home's wall and creating cracks that compromised its stability.

The collapse also resulted in the tipping over of three electric utility poles, which left local residents without power for several hours. Emergency teams from Equatorial Maranhão arrived promptly at the scene to replace the fallen poles and restored electricity by the late afternoon. Local authorities had previously reported concerns regarding the structural integrity of this wall, which was made of stone and clay and had not received adequate maintenance for some time.

This incident raises significant concerns about the preservation of historic structures in São Luís, particularly those that have been neglected. The city's architectural heritage is at stake, and there is a pressing need for funds and attention to prevent such occurrences in the future. Residents had reported risks associated with the wall prior to its collapse, highlighting the ongoing vulnerability of these important historical sites to natural elements and lack of maintenance.
