Stop 1 · India
Agra
The Taj Mahal took some 20,000 workers around 16 years. The city of 1.6 million people around it is a manufacturing hub most visitors never see.
Cities known for a single famous monument
Each stop is a real city with a long history — but for most of the world it is one building, and one building only.
The five stops
Stop 2 · Italy
Pisa
The tower began tilting during construction in 1173 because it sits on soft ground. Engineers straightened it by 45 cm in 2001 and declared it safe for 300 years.
Stop 3 · Spain
Barcelona
Gaudí's Sagrada Família is funded entirely by visitor tickets and donations. It is expected to be finished roughly a century after his death in 1926.
Stop 4 · Greece
Athens
The Parthenon survived largely intact until 1687, when a Venetian shell hit the Ottoman gunpowder stored inside it.
Stop 5 · India
Amritsar
The Harmandir Sahib, or Golden Temple, is Sikhism's holiest site. Its free community kitchen is thought to be the largest in the world.
