To ifanik: Thanks.
 

Thanks for your kind words. The most naturally beautiful place in the world is definitely Australia. It is so physically beautiful. Other places that I REALLY love are:

San Francisco, USA
Archacon, France (shifting sand dune)
Koh Tao, Thailand - small island
Constantinople
The Greek islands - especially Mykonos Town
Kastoria
Monte Carlo

There are so many to list. These are the places that I love the most of all the places that i have visited. For architecture, Europe is the best place to visit. For natural beauty, head to Australia.

Thanks for your encouragement.
