Lost Cities

Tikal was an important capital city of the Mayan Kingdom. The site was occupied for more than 700 years. Tikal National Park is located in Northern Guatemala's Petén Province within a large forest region often referred to as the Maya Forest, which extends into neighbouring Mexico and Belize. The Tikal Ruins, which was established in the years of 1950s, is the central attraction of the Tikal National Park. The site was abandoned by the 10th century after years of occupation.

The ruins of Petra, which is famous for the stone structures built into the rocks, lie southwest of Jordan, on the edges of the the mountainous desert of the Wadi Araba. In 1812, the hidden site was revealed by the Swiss explorer Johann Ludwig Burckhardt. The site, described as 'a rose-red city half as old as time', became a UNESCO World Heritage Site in 1985.

The famous Indus Valley Civilization was the earliest known urban center in present-day Pakistan and western India. The traces of the Indus Valley Civilization were to be discovered first in 1921 at Harappa, located along a dry river Ravi, in the eastern Pakistan. Later traces were found in 1922, at Mohenjo-daro, near the Indus River in the Sindh region. Harappa was an important city with an enormous fortress, built on a raised mound in the West. The rest of the city had a grip pattern of streets. Most houses were laid out around a courtyard. Toilets and Baths were connected to an advanced drainage system.
