Sidewalk Art

I started taking pictures of manhole covers in Spain when I wanted to remember how to spell the Spanish town of Sanxenxo.  Since then I have noticed that they can be quite decorative, and every city has their own design.  Some of these aren't exactly manhole covers, but they are in the sidewalk, so they count...I especially like the butterflies in the sidewalk in front of the Oslo train station.  They are actual butterflies incased in resin.
