Bagan

At its prime, the former city of Bagan on the plains of central Burma was likely a wondrous metropolis of ornate, gleaming temple spires and ritual artistry. But it's possibly even more beautiful and mysterious now that it's a jaw-dropping ruin.

During its heyday around the 12th century, the capital of the Kingdom of Pagan contained well over 10,000 Buddhist temples, stupas, and pagodas. Eventually, the city was brought to ruin by natural disasters and hordes of Mongols, who made light work of the city's Buddhist inhabitants.

Through the centuries, thousands of the temples and pagodas crumbled under their own weight or were destroyed, leaving only a little over 2,000 of the structures today. However, this has done little to diminish the scope of the city's grandeur.

The almost impossibly ornate temples that survive rise up out of the overgrown foliage. The structures, which burst from the plains, look like the creations of a lost civilization. While that is not strictly true, as many of the inhabitants of Bagan would sire the generations that created modern Myanmar, a sense of mystery still pervades the city.

Still covering 26 square miles of land, the thousands of ruined temples and religious monuments are now a protected historical site. While some of the structures have fallen into complete disrepair, many others almost look as if they haven't aged a day, thanks to modern restoration efforts.
