The most densely populated place on Earth

With 20,497 individuals per square kilometer, Macau has the world's highest population density. It's no surprise that it needs to do something spectacular to make place for more casinos and the 30 million annual visitors. A huge land reclamation project connecting the two islands south of the mainland, Coloane and Taipa, was the solution. This added 5.2 square kilometers to Macau, allowing it to become a gambling mecca to rival Las Vegas.

The Cotai Strip gets its name from the names of the two islands, Coloane and Taipa.The Cotai Strip is home to the Venetian Resort, City of Dreams, Sands Cotai, and Galaxy Macau Resort. Another major one is on the way: Steve Wynn is spending $4 billion on Wynn Palace, a massive resort that will open in 2016.

Many tiny parks with statues and unique artwork may be found throughout the city. Aside from the Fisherman's Wharf, there are other museums and commercial districts worth visiting.

Senado Square, or Senate Square, is perhaps the most well-known of Macau's many local attractions. In the 16th and 17th centuries, a local senatorial body met there. This is a world heritage site that is only accessible by foot. Senado Square, which has been used in a variety of film sets, was originally a spot where governors evaluated their troops.

Tourists visit the Ruins of St. Paul, which were formerly a church and college, as well as local shops around the plaza.
