Each stone block fits together without mortar, showing careful planning and skilled craftsmanship. Scholars still do not know how ancient builders moved and lifted over two million stone blocks without modern machines.
The temple’s unique design, which looks like stacked platforms topped by a dome, follows complex mathematical and spiritual ideas. Its construction methods and symbolic layout remain a subject of study.

It caused tsunamis, destroyed thousands of villages, and killed over 36,000 people. A strange phenomenon followed: the “sea of fire,” where hot ash and lava turned the nearby waters red and boiling.
The sun appeared blue and sunsets were seen as far away as Europe and America. People still debate the exact reasons for the eruption’s intensity and the unusual atmospheric effects.
