While I was browsing the interwebs one morning, I came across a very intriguing website: Atlas Obscura. Basically it seems to document any- and everything about our planet which could be considered beautiful, mysterious, horrific and artistic. You can check out an amazing salt mine in Poland, complete with chandeliers; a beach in Brooklyn covered in tumbled sea glass and pottery; an entire city of pigeon houses - many larger than human abodes; a blood-red waterfall, and the horrifying and heart-breaking Great Pacific Garbage Patch.
So if you have some spare time and curiosity, I highly recommend this amazingly well-documented website. Let me know what interesting things you find!
