The WordPress Weekly Photo Challenge has the theme of Rounded. The first entry that I put together for this challenge was from Nature, so why not one that is man-made this time?
There is a lot of structures that are rounded, as the arch is one of the quintessential load-distribution mechanisms in architecture. The arch spans a large area by resolving downward forces into compressive stresses along its curved shape. The first arches appeared in the 2nd millennium BCE in Mesopotamia and were perfected by the Romans to build structures that still stand across the ages.
Take a look back into history with the set of arches on display here…
The Colosseum has withstood both time and earthquakes (and pollution) to still stand proud in the 21st century!
Have a wonderful day!
