What were the parts of the lighthouse of Alexandria called?

The Lighthouse of Alexandria, also known as the Pharos of Alexandria, was structured in three main tiers: the square base, the middle octagonal section, and the circular top section. It featured a large open flame at the summit, which served as a beacon for sailors. The lighthouse was adorned with statues, including one of Zeus or Poseidon, and was constructed on the island of Pharos in ancient Egypt around the 3rd century BCE.
