There is a darling little hillside medieval village in Second Life called SaliMar. I love the design...all stairs and narrow alleys with small courtyards surprising you around the corner. But the best part - for me at least, was encountering the work of the sculpter Nessuno Myoo. The pieces are clever, whimsical, attractive and thought provoking.
Gallery (for some reason I'm assuming the sculpter is a "he", I apologize if I'm mistaken) which I enjoyed but honestly the pieces have a much better setting in this little village.
I really need to get shadows working to do these sculptures justice - go see them in person and then see the show in November at The Aho Museum. It's well worth the effort and you will thank me. :)
