5 lost cities that have been found

Archeologists have recently discovered a lost Mayan city in the Mexican jungle -- so here are five lost cities you need to know about.

1. Lagunita
An archeologist from Research Center of the Slovenian Academy of Sciences and Arts rediscovered the lost Mayan city of Lagunita. He identified a Mayan doorway, the remains of massive buildings, plazas, ball courts, a pyramid and three altars that date back to 711 AD. How cool is that?

2. Helike
In the year 373 BC, a giant earthquake hit off the coast of Greece, which created a giant tsunami that swallowed the ancient city of Helike. Then, in 2001 a team finally rediscovered Helike, digging up coins, pottery and ruins. The reason it took them so long to find it, was because they were looking in the water, but it was under dirt! The water had dried up!

3. Troy
Yes, the famous city of Troy was once lost. In fact, a lot of people thought in never existed. But then, Heinrich Schliemann went on quite adventure in 1870, following clues laid out in Homer's the Iliad and dug that city up.

4. Pavlopetri
This is the real life Atlantis. Thes 5,000-year-old lost city was found in 1967 and is thought to have been submerged about 3,000 years ago. So, it had a good run. Archeologists found roads, buildings, courtyards and pottery.

5. Machu Pichu
Maybe the greatest lost city sits on top of a mountain in Peru. It wasn't rediscovered until 1911 mostly because of its location. People are always digging for lost cities, or trekking through the jungle. No one thinks to look up.
