The Pharos of Alexandria started with a large box-like structure at its base, about 200 feet high and 100 feet square. Above this was an octagonal (eight-sided) tower from which protruded a cylinder extending up to an open cupola. The actual light of the lighthouse was a fire that burned in this cupola. On the roof of the cupola was a large statue of Poseidon. The building was made of marble blocks, using lead mortar.

How do I build a cupola
Yes. The adjective is spelled "octagonal" (having 8 sides).
An octagonal prism has two parallel faces that are octagons and parallelograms connecting them. A rectangular prism is like a box.
In geometry, the octagonal prism is the sixth in an infinite set of prisms, formed by square sides and two regular octagon caps. Pencils and kaleidoscopes are shaped like octagonal prisms.
Domed building rotunda
It's an octagon. Look at a stop sign- they're octagonal.
An octagonal prism is a geometric shape with eight faces that are octagons. Some common objects that are shaped like an octagonal prism include certain types of crystals, such as beryl or fluorite, as well as certain types of nuts and bolts. In architecture, some buildings may feature octagonal prism-shaped elements, such as towers or spires. Overall, objects shaped like an octagonal prism are typically characterized by their eight flat sides and two parallel, congruent octagonal bases.
The Pharos lighthouse was also known as the Lighthouse of Alexandria. It was an impressive stone and marble structure situated on a stone foundation and believed to be between 450 and 600 feet high, or 300 cubits in ancient measurements. The Pharos was one of the wonders of the ancient world. The base of the Pharos was shaped like a huge box, up to 200 feet high and 100 feet square. Atop this was an octagonal tower, from which protruded a cylinder extending up to an open cupola. The actual light of the lighthouse was a fire that burned in this cupola. On the roof of the cupola was a large statue of Poseidon. See the related link below for more information, and images.
