[Updated 3 p.m. Monday, August 20] Tourists in a balloon fly over Prague Castle, one of the world's largest medieval castle complexes at nearly 70,000 square meters (753,000 square feet).
The Czech tourist attraction, a UNESCO World Heritage site, was likely founded in the ninth century. Through the years, it has been home to kings, emperors and presidents. The Czech Crown Jewels are also held on the premises. Click here to see more photos and more information about the site, including visiting hours.
Congrats to Lance Finney and Timodeus for being the first to answer Prague in the comment section below.
[Original post] Do you know where this photo was taken?
If you think you know the answer -- or if you just want to take a wild guess -- post it in the comments area below. Later in the day, we'll reveal where the photo was taken and give credit to those who figured it out first. (The more detail, the better!)
Each Monday morning, we'll post a new photo and challenge you to tell us its origin. The photo might be related to a prominent news story or theme -- or it might just be something that caught our eye.
