A 9-foot-thick foundation clearly wasn't enough to support the 183-foot bell tower at the city cathedral in Pisa, Italy, as evidenced by its 4-degree lean. While Mussolini tried to fix the tower when he was in power, his efforts actually made things worse. Millions of dollars were spent on restoration in the late 20th century, stabilizing the structure.

Leaning a full degree further off-kilter than the Leaning Tower of Pisa, the 90-foot-tall brick tower at Suurhusen in Germany tilts at a whopping 5 degrees. Built in the 15th century on a foundation of oak tree trunks, the structure's severe tilt is at least somewhat camouflaged by the surrounding trees.

Believe it or not, even the iconic Palace of Westminster Clock Tower in London, England, has a slight slant. Completed in 1859 using brick, limestone and cast iron, its top is 9 inches away from pointing straight up at the sky.

The Petronas Towers in Kuala Lumpur, Malaysia, became the tallest twin towers in the world when they were completed in 2004. Outside of the capital, the Teluk Intan Tower along the Perak River is also worth seeing. While only 85 feet tall, it has a distinctive tilt, thanks to soft ground and a heavy, unbalanced tank used for storing water.

Since it was completed in the 13th century, the leaning tower of Torun, Poland, has served as a defensive tower, a prison and a cafe.

Iraq's Minaret of the Great Mosque of al-Nuri was built in the 12th century, but it was both tilted and marred by a bulge that earned it the nickname "the hunchback." After standing for centuries, the 148-foot tall structure was mostly destroyed in the 2017 Battle of Mosul.

The Chesapeake Bay meanders through Maryland on the east coast of the U.S. In 1881, the Sharps Island lighthouse was hit by an ice floe and carried off down the bay with its keepers trapped inside. Rebuilt the next year, the lighthouse was hit by another chunk of ice in the 1970s. This collision knocked the structure 15 degrees off-center, but it stayed firmly in one spot. These days, the entire Sharps Island is submerged.

The Torre delle Milizie or Tower of the Militia was built around the year 1200 in Rome, Italy.

The town of Chesterfield, England, is home to the massive Church of St. Mary. This 14th-century Gothic structure has a 228-foot spire at the top that twists and leans to one side. This twist could be the result of a sneeze by the Devil, as some claim, or it may simply be due to a lack of structural support. Many people died of the Plague during the time it was constructed, and it's possible that the work was completed by inexperienced carpenters.

To accommodate a new Disney theme park in Shanghai, the Chinese government built new housing in Pudong to relocate citizens away from land zoned for the park. Unfortunately, those who moved into Buildings #17 and 18 in the Xinyuan West Community found that the twin 15-story buildings shared a foundation. This caused them to lean and eventually butt into one another along the roofline.

A Buddhist temple made from cast iron, the Iron Tower of Yuquan in northern China tilts 1.5 degrees to the north. Some theorize that this lean was part of the design, intending to help the tower withstand strong winds from the north. Considering it's still standing 1,000 years after it was built, the engineering team must have known what they were doing.

Though Britten's truck stop burned down long ago, the leaning water tower of Groom still draws visitors on this stretch of old Route 66.

Most towers in this quiz have a lean that's not necessarily seen as a good thing. In the case of the Dancing House in Prague, Czech Republic, however, the extreme lean is the product of a creative design team. Now serving as the headquarters of Nationale Nederlanden, the fabulous leaning building was designed in the Deconstructivist style by none other than Frank Gehry and Czech engineer Vlado Milunic.
