Walled City of Dubrovnik
Dubrovnik is Croatia's leading tourist attraction, a historic
walled city-state and maritime power that remained
independent for hundreds of years.  It finally surrendered to
Napoleon.  But Dubrovnik's walls were battered by
Yugoslavian Army shelling during the civil war, as Serbia
sought to destroy Croatia's symbols and economy.  Croatia
has since rebuilt Dubrovnik, which again plays host to
countless visitors arriving on cruise ships.     
Dubrovnik's walls are among the most massive I ever recall
seeing.  The thickness of these sea walls and scale of the
overall fortifications can best be viewed from a photographic
perch above the city, from which these first two pictures were
taken.  The small boat harbor is also very attractive, offering
cruises to view the walls at sea level.  Rough water canceled
that opportunity for me.    
The entrance to Dubrovnik is a forest of walls, none of which
prevent the city from being mobbed by tourists.  The crowds
were overwhelming, from seven cruise ships I believe.   
Dubrovnik's buildings, such as this clock/bell tower, tend to
imitate those of its ancient rival, Venice.  As with Venice,
tourist invasions seem to be driving out the local residents.
