Leaning Tower of Pisa’s Worn Steps

Italy’s Leaning Tower of Pisa requires visitors to climb 296 steps in order to reach its peak and the awaiting seven historic bells tuned to the musical scale.
As you can see here, that feat of physical endurance has been attempted by thousands of individuals since the construction of the tower began in 1173. It is estimated over one million people visit the tower each year.
Although not all of them make the upwards trek these stairs show that, despite the lean, the tower was built to last.
A Power Washed New York City Building

Life in the big city is not as perfect as we see it in the movies. If you ever go to New York City, one thing you may notice are some streets lined with darkened buildings.
They are rather bleak-looking because of the city’s history with air pollution. This picture showcases a New York building before and after power washing. This is as a result of the days when coal plants were the norm.
