13 historic monuments, puzzles which are still not solved

Tikal, Guatemala

One of the largest settlements of the Maya lurking in green jungle. Here there are artificial ponds, and a golf ball, and palaces. But special attention – the pyramids, forming a town square. They built their temporary pattern corresponding to the periods of its development. Theories about their functions are many: religious buildings, research centers, cemeteries or both. Unclear and the etymology of the name “Tikal”. But there is a clear “nickname” – City of votes. Because even the whisper of it is given to echoing.
