Spanish galleons were large, multi-decked sailing ships used by the Spanish Empire from the 16th to the 18th centuries. These ships were designed for long voyages across the Atlantic Ocean and were primarily used for trade and transporting valuable goods, such as gold and silver from the Americas back to Spain. Their sturdy construction and advanced sailing technology made them essential for maritime exploration and commerce. The galleons were often heavily armed to protect against pirates and rival nations. They played a crucial role in the Spanish treasure fleet, which transported wealth from the New World. The legacy of these majestic ships continues to capture the imagination of historians and enthusiasts alike.
