1. Lost Civilizations: Petra, Jordan

Does this rose-colored beauty look familiar? Petra, Jordan, played a starring role in the film “Indiana Jones and the Last Crusade.” The city was established around the sixth century B.C. as the capital city of the Nabataeans, but went into decline under Roman rule. In 363, an earthquake destroyed many buildings and crippled its water management system. Travelers can ride camels and admire the gorgeous facades of the Treasury and the Monastery, in addition to a 7,000-seat Roman theater. Be sure to note the urn atop the Treasury structure; it is rumored to contain a pharaoh's hidden treasure. In 1985, Petra was designated a World Heritage Site. It is now the most visited tourist attraction in Jordan.

2. Lost Civilizations: The Minoans of Crete

The Minoans were a Bronze Age civilization who lived on the island of Crete
in Greece. They flourished from the 27th century B.C. to the 15th
century B.C. The Minoans had a written language, agriculture, pottery,
painting and a religion in which they worshipped primarily goddesses.
What happened to this civilization? No one knows for sure, but the
eruption of nearby Thera, aka Santorini, was one of the largest volcanic
events in recorded history and may have contributed to the Minoans’
downfall. Visitors to the walled city of Heraklion, the capital of
Crete, can visit an archaeological museum that holds Minoan remains.
Also worth seeing is the Minoan Palace of Knossos, connected with
legends such as the myth of the labyrinth and the Minotaur, as well as
the story of Daedalus and Icarus.
3. Lost Civilizations: Easter Island

Easter Island
is one of the most isolated places in the world — 2,300 miles from
Chile and 1,300 miles from the Pitcairn Islands. Scientists have long
puzzled over how the hundreds of 30-foot-high statues came to be, given
that the prehistoric population had no machines, no metal tools and no
draft animals. What remains today is a tiny population of fewer than
4,000 people of Polynesian descent and immigrants from Chile, as well as
the mystery of the giant stone statues. In his book “Collapse: How
Societies Choose to Fail or Succeed,” author Jared Diamond suggests that
ecological destruction led to this civilization’s demise.
4. Lost Civilizations: Chichen Itza

Long before Christopher Columbus arrived in the Americas, the Mayans built Chichen Itza
on the Yucatán peninsula in Mexico. Chichen Itza fell by around the
year 1000. The site still contains fine stone buildings, including
pyramids, and a network of formerly paved roads. It also contains the
Great Ball Court, the largest of its kind in ancient Mesoamerica. Now a
popular day trip for visitors to Cancun, Chichen Itza has been a tourist
destination for more than a century.
5. Lost Civilizations: Mesa Verde

Mesa Verde,
Spanish for “green table,” is in Colorado and offers a peek into the
lives of the Ancestral Pueblo people who made it their home from
the seventh to the 14th century. Then, in the span of a generation or
two, they left their homes and moved away, for unknown reasons. Today,
Mesa Verde National Park protects more than 4,000 known archaeological
sites, including 600 cliff dwellings. Descendants of Mesa Verde
Ancestral Puebloans include the Hopi in Arizona and the 19 Rio Grande
pueblos of New Mexico.
6. Lost Civilizations: The Vikings

The
Vikings got around. These Scandinavian seamen, warriors and merchants
traveled in their longships as far as Russia, Spain, Italy, the Middle
East, North Africa, Iceland, Greenland and Newfoundland, between the
eighth and the 11th century. For one look at their past, visit Jarlshof in Shetland, Scotland,
which boasts seven buildings, including the first confirmed Norse
longhouse in the British Isles. Excavators also discovered iron tools
such as shears, scissors, sickles and a fish-hook and knife. If you
prefer a hands-on experience, consider rowing a Viking ship replica at
the Viking Ship Museum in Roskilde, Denmark.
7. Lost Civilizations: Pompeii

When Mount Vesuvius erupted in the year 79, it buried Pompeii, Italy,
under ash and pumice. The city was lost for more than 1,500 years
before it was rediscovered in 1592. Today’s visitors can peer at
excavated villas, an amphitheater, an aqueduct and street fountains,
businesses and public baths. Plaster casts of victims who died reveal
the expressions on their faces, the folds of their clothes and the
contorted positions in which they perished. Pompeii is a UNESCO World
Heritage Site and now attracts 2.5 million visitors annually.
8. Lost Civilizations: Angkor Wat

This temple complex in Angkor, Cambodia,
was built in the 12th century for King Suryavarman II as the capital of
the Khmer Empire. Initially a Hindu temple, it eventually became a
Buddhist one. In his book “Collapse: How Societies Choose to Fail or
Succeed,” author Jared Diamond suggests that Angkor Wat may have gone
into decline due to the silting up of reservoirs that supplied water for
rice agriculture. The temple complex is now a major tourist destination
and has been a UNESCO World Heritage site since 1992.
9. Lost Civilizations: Machu Picchu, Peru

If you’re traveling to Peru, don’t miss visiting the Incan ruins at Machu Picchu,
a vital link to the Americas’ pre-Columbian heritage. The site was
built starting around 1400, but was not inhabited for long — its
residents cut their time short when the Spanish invaded a century later.
Few knew of its existence until 1911, when American archaeologist Hiram
Bingham first brought it to international attention. In April 2010,
tourists returned to Machu Picchu, which reopened after a two-month
closure due to floods that washed out the rail link to the mountaintop
ruins.

11. Lost Civilizations: Tikal

Tikal, Guatemala,
was one of the most powerful kingdoms of the ancient Maya. It was
inhabited from the sixth century B.C. to the 10th century A.D. This
UNESCO World Heritage site contains the remains of 230-foot-tall
temples, large royal palaces, pyramids, residences, administrative
buildings and inscribed stone monuments. Tikal had no water other than
that collected from rainwater and stored in reservoirs. The reliance on
seasonal rainfall left the city vulnerable to drought, which likely
played a role in its eventual collapse.
12. Lost Civilizations: Troy (Troia), Turkey
