"On April 26, 1717, the Whydah Gally went down off the coast of Cape Cod — taking her crew, her treasure, and her secrets to the bottom. She lay undiscovered for 267 years." -https://www.discoverpirates.com/expedition-whydah/
The Whydah Gally was crafted in London in 1715 with the intended purpose of transporting slaves. While on her maiden voyage south of the Bahamas, the ship was captured by notorious pirate Captain "Black" Sam Bellamy. Having recognized the ships potential for speed, firepower, and cargo capacity, Bellamy reimagined the Gally as his newest flagship.
Bellamy was an extremely successful pirate who amassed great wealth by capturing ships from all across the Atlantic. Though the Whydah's hold was loaded with unimaginable treasure, Bellamy never got the chance to enjoy it in retirement.
During one severe storm along America's New England Coast, the Whydah became hopelessly entrenched in a sandbank. All but two of the Whydah's crew members drowned. The rest of Bellamy's fleet didn't fare much better. Those who survived the battering of the storm, were ultimately taken into custody by New England authorities and sentenced to hang.
Fortunately, the location of Whydah's wreckage was documented by Bay Colony Captain Cyprian Southack, who was also a reputable cartographer. Unfortunately for later treasure seekers, sandbanks tend to shift. This constant movement makes the rediscovering of objects even the size of ocean going vessels, extremely difficult.
Deep sea explorer Barry Clifford and his team re-discovered the Whydah during an excursion off Cape Cod in 1984. It is the first truly authenticated pirate shipwreck ever discovered. (They can make this statement because they found both the Whydah's bell and a brass placard with the Whydah's name and maiden voyage date on it which serves to verify the ships identity. Other wreck sites, such as Black Beard's Queen Anne's Revenge off the coast of the Carolina's, can't boast of having that kind of verification.)
Priceless artifacts from the wreck are currently on display at Real Pirates Salem, a pirate themed museum in Salem, MA. Clifford Barry's exploration of the wreckage and retrieval of artifacts is ongoing.

Though Bellamy saved the ship from its original dreadful purpose, it didn't save her from suffering a gloomy end. But then as fate would have it, the Whydah is enjoying fame in a new era. History is literally being made as we watch from the sidelines.
