‘Hedgehogs’ vs tanks: Ukraine capital Kyiv braces for Russian onslaught
- Civilians in Kyiv build home-made defences ahead of anticipated Russian assault
- ‘Hedgehog’ anti-tank obstacles were used in several countries during World War II

As Russian troops closed in on Ukraine’s capital Kyiv this week, a muddy construction site in a local neighbourhood was teeming with workers and welders of the KAN real estate developer.
Instead of homes and offices, they were making giant, metal anti-tank barricades known as “hedgehogs”, and smaller spiked barriers aimed at stopping wheeled vehicles.
“Hedgehog” anti-tank obstacles were used in several countries during World War II.
After Russia invaded Ukraine on February 24, KAN, a large local property company, reinvented itself to help the defences of the city of 3.4 million people.
Zakhar, a foreman, picked up the phone and started calling the company’s construction workers who had remained in Kyiv. Almost everyone volunteered to stay and contribute, he said.
“We build things. We do not know how to fight, but we knew we could be useful,” Zakhar said. A few metres away sparks flew as builders cut through and welded together large metal beams.
