Remarkably, artifacts and architectural relics from the outpost attested to its historical significance as the earliest European settlement in North America. Even though the structures appeared to have been used for a long time, Indigenous people were probably the reason they were abandoned.

Subsequently, researchers found a six-acre African burial site containing over 15,000 complete corpses, providing insight into the nation’s sordid colonial past. Their causes of death were never determined, however the remains were believed to have been from between 1630 and 1795.

When a tooth, a 1.22-meter femur bone, and many other bone fragments were discovered during construction, the construction workers were taken aback to discover that they were all from a mammoth that lived thousands of years ago during the Ice Age.
