Badgers build underground fortresses with many doors

European badgers are master architects, digging complex underground homes called setts. These setts often boast multiple entrances, sometimes over 30, acting as vital escape routes from predators like foxes or wolves. This clever design ensures family safety and good ventilation within tunnels that can stretch for hundreds of meters. Some setts have been continuously occupied for over 200 years, offering a fascinating glimpse into ancient landscapes.
