Have you heard of love locks? A local bridge in Prague is adjourned with countless locks. The bridge is just around the corner from the John Lennon Peace Wall. The bridge and Peace Wall are located in the Castle District. It took a while to find - but was well worth the effort.
My son-in-law, Warren, is an iron/glass worker. On my recent visit to Chicago, my daughter, granddaughters and I took an architectural tour on the Chicago River. We passed beneath Warren's building. Even though I couldn't see him from the boat, I took a photo and found him once I enlarged the photo. (The building was so tall, I couldn't get the whole thing in the photo from the boat with the lens I had with me.)
The guy is amazing - can you image working up so high?!
