It has been just a little of a year since the Grenfell Tower fire. It was the greatest loss of life in a fire on British soil since World War II, a horror that left the neighborhood and the country in shock. The anniversary was marked by a minute of silence, vigils and marches across Britain and landmarks were lit up in green, the colour of remembrance adopted after the lethal fire.

Fire and rescue services were overwhelmed when they arrived at the raging, out of control fire that night. They had been called out at 1 a.m. and within minutes, the flames had escaped Kebede’s apartment and raced up the outside of the 25-story tower like a lit fuse. High-rise apartment towers are supposed to be designed to stop apartment fires spreading. This wasn’t the case with Grenfell Tower.

Several people died trying to get out. Others perished in their homes as they waited to be rescued or died in neighbours’ apartments where they’d taken shelter. Three people were found dead outside, having fallen or jumped from the tower. 72 people in total died in that fire.

Many residents said they had complained about safety and poor maintenance and were ignored because the tower was home to a largely immigrant and working-class population. A public-housing block in one of London’s richest boroughs, a stones’ throw from the pricey boutiques and elegant houses of Notting Hill, it came for many to symbolize a divided and broken Britain.

A judge-led public inquiry finally got underway in May of this year. It will take 18 months and look at the fire’s causes, the response to it and Britain’s high-rise building regulations. Already, the testimony has been damning. A report by fire safety engineer Barbara Lane listed multiple safety failings, including the flammable aluminum-and polyethylene cladding installed on the tower’s facade during a recent renovation.

The safety failures at Grenfell have national implications. More than 300 towers around Britain have similar combustible cladding. The government says it will spend 400 million pounds ($530 million) stripping the cladding from publicly owned high-rises. Even if the inquiry identifies causes and who deserves to be held accountable, the formal review is unlikely to end Britain’s soul-searching over a disaster with victims from 23 countries — taxi drivers and architects, a poet, an acclaimed young artist, retirees and children with bright futures.
