I am in Tallin Estonia, very beautiful smaller city, nice change from Berlin. There are some really old towers right down the street with the slat type holes for bow and arrow or guns. I will try to inspect in the morning. They appear to construct the older ones out of some type of loose compressed limestone, you can sort of see shell, it is dark already so I could be all wrong.
Easyjet.com is really a good Airlines, clean, efficient and cheap, the future of all Airlines I believe.
