The main strip of Dubrovnik is Stradun St., with shopes, nice restaruants, and bars that you can frequent. It’s very nice to walk along, but I would suggest getting food and other wares from shops off the beaten path, which you will find to be cheaper. Nonetheless, this area is ideal for people watching.
The Vatican museums are full of rich history in the form of tapestries, maps, artwork, sculptures, and painting. What I actually enjoyed the most though was the Bramante Staircase at the end of the Vatican tour we had. I loved the symmetry of this double helix staircase and tried to capture as much as I could of it with my wide angle lens.
