Lost Cities is a 60-card card game, designed in 1999 by game designer Reiner Knizia and published by several publishers.
 The objective of the game is to mount profitable expeditions to one or more of the five lost cities (the Himalayas, the Brazilian Rain Forest, the Desert Sands, the Ancient Volcanos and Neptune's Realm).
 The game was originally intended as a 2-player game, but rule variants have been contributed by fans to allow 1 or 2 further players, causing Reiner Knizia himself to later provide semi-official 4-player rules.

 The United States ranked 88/158 on the Global Peace index for 2012.
 The U.S. index was released on 6 April 2011, at 00:01 Eastern Time and the second edition released on 24 April 2012.

A lost city is a settlement that fell into terminal decline and became extensively or completely uninhabited, with the consequence that the site's former significance was no longer known to the wider world.
 The locations of many lost cities have been forgotten, but some have been rediscovered and studied extensively by scientists.
 Recently abandoned cities or cities whose location was never in question might be referred to as ruins or ghost towns.
 The search for such lost cities by European explorers and adventurers in Africa, the Americas, and Southeast Asia from the 15th century onwards eventually led to the development of archaeology.
Viscount Powerscourt ( ) is a title that has been created three times in the Peerage of Ireland, each time for members of the Wingfield family.
 It was created first in 1618 for the Chief Governor of Ireland, Richard Wingfield.
 However, this creation became extinct on his death in 1634.
 It was created a second time in 1665 for Folliott Wingfield.
 He was the great-great-grandson of George Wingfield, uncle of the first Viscount of the 1618 creation.
 However, the 1665 creation also became extinct on the death of its first holder in 1717.
In the popular imagination lost cities are real, prosperous, well-populated areas of human habitation that have fallen into terminal decline and been lost to history.
 Most real lost cities are of ancient origins, and have been studied extensively by archaeologists.
 Abandoned urban sites of relatively recent origin are generally referred to as ghost towns.
