This might not be street are in modern terms, but it's still pretty amazing. The Monument to the Explorers in Belém, Lisbon is an awesome tribute to exploration and navigation. I made a guide to help you navigate the who's who of this cool structure.
Both the bottles were painted from inside. Although this may sound difficult to do, but the trick is to put some oil paint in the bottle and then roll the bottle till the paint is uniformly spread on the inside. After this, put the bottle upside down so that the excess paint comes out. After allow the paint to dry for a day. Since the bottle was painted from inside, it gives a nice finished look.
