According to Antoine Gigal a French writer, researcher and explorer there are around 30 pyramids and most of them are placed around the volcano of Mount Etna. There are step pyramids, square step pyramids, rectangular pyramids with rounded corners and curved steps and round conical step pyramids. Instead of their form all of these pyramids are constructed from the lava stone from the Mount Etna and have a lot of similarities with the Tenerife pyramids in their form, size and construction material.
No official archaeological research dates about these pyramids construction on the Internet.
