How was the temple of Chinchen Itza built?

The Temple of Chichen Itza, also known as El Castillo, was built by the Maya civilization between the 9th and 12th centuries. Constructed primarily from limestone, it features a step pyramid design with 91 steps on each of its four sides, symbolizing the 365 days of the year.
