Where was world war 2 secret code broken?

World War II secret codes were notably broken at Bletchley Park in the United Kingdom, where a team of cryptanalysts, including Alan Turing, worked to decipher the German Enigma machine codes. This intelligence breakthrough significantly contributed to the Allied war effort by providing crucial information about enemy plans and movements. Additionally, other locations in the U.S. and Europe also played roles in code-breaking efforts, but Bletchley Park remains the most famous site associated with this achievement.
