Why did it take 15 years to build the Parthenon?

The Parthenon took 15 years to build, from 447 to 432 BCE, due to its massive scale, intricate design, and the advanced architectural techniques employed. Constructed during the height of the Athenian Empire under Pericles, it required skilled labor and high-quality materials, which contributed to the lengthy process. Additionally, the project faced challenges such as political instability and the need for meticulous craftsmanship to achieve its artistic and structural perfection.
