Archaeology provides insights into how the world came to be what it is today, and every discovery has the potential to improve our understanding of the past. In June 2021, Russian archaeologists found a Cave Bear skeleton with a small hole in the back of its head, which experts believe was caused by a spear, possibly the earliest evidence of humans deliberately hunting Cave Bears.

In Poland, road workers discovered a 100-meter-long wooden road beneath the current road surface, believed to be an 18th-century passageway leading to the city gate. Historians have long assumed that the Romans used and kept slaves during their occupation of Britain, but it was difficult to find direct evidence.

However, in April 2021, builders discovered a shackled skeleton of a man buried deep below a house in Great Certon Rutland, the only known Roman-era example of someone being buried with iron feets attached to his ankles.

Lastly, the blue stones of Stonehenge, quarried from the Preseli Hills in Pembrokeshire, Wales, have puzzled archaeologists for years. In 2019, researchers pinpointed the precise location where the stones were taken from and discovered human-made stone and wood platforms used to transport them.
