Treasure ships were large vessels used primarily during the Age of Exploration to transport valuable goods, such as gold, silver, and spices. These ships played a crucial role in trade between Europe, Asia, and the Americas, often carrying precious cargo from colonies back to their home countries. Many treasure ships were targeted by pirates and rival nations due to their valuable cargo. Notable examples include the Spanish galleons, which sailed the Caribbean Sea and were known for their riches. The sinking of some of these ships has led to modern treasure hunting and exploration efforts.
