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.
Treasure was a syndicated American television series created in 1958 by Bill Burrud Productions.
 The series originally aired on KCOP-TV.
 It filmed documentaries on buried treasure, lost cities, shipwrecks, and ghost towns.
The city of Pavlopetri (Greek: Παυλοπέτρι ), underwater off the coast of southern Laconia in Peloponnese, Greece, is about 5,000 years old, and one of the oldest submerged lost cities and the oldest in the Mediterranean sea.
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.
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.
