Basilica Cistern

Built in 532 AD, the cistern was used to store water for the Great Palace of Constantinople and other buildings.

Paris Catacombs

In the late 18th century,Parishad a dire public health problem due to a large number of unburied corpses. Parisians sought the solution underground in quarries that had supplied therock to build the city. Six million skeletons were exhumed and arranged in thecatacombs, which are as deep as a five-story building, and include artistic arrangements of skulls and bones — don't miss the giant urns made of skeletal remains. Although much of the 200-mile network is out-of-bounds to the public, the 45-minute tour is a great peek. Make sure to arrive early, as the attraction is incredibly popular.

City Hall Subway Station

For a ghostly architectural gem inNew York City, hop on the downtown 6 train and stay on past the end of the line at Brooklyn Bridge. As the train loops around, you'll pass by gorgeously decorated arches, skylights, intricate colored glass tilework and burnished brass light fixtures in the now-unused City Hall station. The station was opened in 1904 and was meant to be the crown jewel of the new subway, but due to low traffic numbers and an unsafe gap at the platform, the station was closed in 1945. The mystique and spooky, abandoned beauty of this hidden jewel is well worth the train ride.

The Cu Chi Tunnels

During the Vietnam War, the communist guerilla Viet Cong were vastly outnumbered and equipped with inferior technology compared to the American and South Vietnamese troops. To combat this, the Viet Cong expandedtunnelscreated during an earlier war against the French, and used these underground routes to house troops, transport supplies, and lay booby traps. The residents of Cu Chi slept, ate, wed, and even gave birth in these underground abodes to avoid detection. While getting to the tunnels is a bit of a trek (expect a 2.5-hour bus ride from Ho Chi Minh city), the tour and tunnels are an amazing sight. Make a day out of it by combining the tunnel tour with a trip to the nearby elaborate Cao Dai Temple.

Capuchin Crypt

For one of the eeriest sights in the world, visit Rome'sCapuchin Crypt. Beneath the church of Santa Maria, you'll find the skeletal remains of 3,700 Capuchin friars. In 1631, when the monks moved to the church, they brought cartloads of deceased friars to be arranged in the burial crypt. Over the course of years, a cyclical process developed where long-dead friars were exhumed to make room for recently deceased friars' burials, the exhumed bones were then placed into the crypts' elaborate designs. What makes this crypt more chilling than the Paris Catacombs is the true artistry and intricate displays in the six crypts. Enter the crypt and gaze upon artwork all framed by various human bones, skull chandeliers, and intricate bone designs. Visitors must wear modest clothing and be prepared for a macabre scene.
