The Largest Sword Ever Used in Battle: 5 Most Massive Ancient Weapons 

This is the Sword of Pier Gerlofs Donia-a sword built for a giant and perhaps the largest sword ever wielded in battle.
The sword belonged to Pier Gerlofs Donia, a rebel and pirate from Frisia in the Northern Netherlands, whose exploits and incredible size made him a legend. Pier was so large that he became known by his nickname, Grutte Pier, or 'Big Pier.'
Born around 1480, Pier is described as standing around 7 feet tall, possessing such immense strength that he reportedly could bend a coin with just his thumb and forefinger. Some tales even claim he once lifted an entire plow with a single hand.
At the age of 18, Pier witnessed Frisia's transition into a free nation following a prolonged civil war between the Schieringers and the Vetkopers. Although the Schieringers had officially won, the Vetkopers continued to resist, leveraging international connections for support.
While skirmishes periodically flared up in distant regions, Pier managed to marry and lead a contented life as a prosperous farmer.
This idyllic existence lasted until 1515 when, at the age of 35, Pier’s life was irrevocably shattered as the Black Band, a group of Saxon raiders employed by the Vetkopers, ravaged his hometown, brutally killing his wife and torching his farm.
Rising from the ashes of his former life, Pier embarked on a path of cataclysmic vengeance, marking the beginning of his legendary exploits as the leader of a pirate army targeting Saxon occupiers and transforming him into a figure of mythic retribution.
Pier quickly became known for wielding a two-handed sword as long as he was tall and weighing almost 16 pounds. The sword is believed to have been crafted in Germany and may have been seized from a Saxon foe.
For comparison, the typical 16th-century Zweihänder sword, the largest standard two-handed sword of the day, measured around four and a half feet long and weighed just 4 pounds.
Despite the myriad legends surrounding him and his mighty sword, Grutte Pier eventually recognized the futility of his struggle, retired from his life of rebellion, and passed away shortly thereafter.
Skeptics have questioned the authenticity of the sword currently housed in the Fries Museum, suggesting it might be a ceremonial bearing sword from the 1400s, too unwieldy for practical use.
Nonetheless, new research by the museum supports the notion that Grutte Pier indeed wielded this epic weapon in combat, adding a layer of historical credibility to the legendary narratives surrounding this imposing figure...
