I am glad you could see some of the wonders of Europe, especially from being from the US. Thanks for pictures. We recently spent some time at the University of Coimbra in Portugal, founded in 1290 which is pretty old by any standard. Portugal doesn't get a lot of US travelers for some reason, it is a great old country that pretty much dodged the 20th Century European land wars and most of the really old stuff is still standing, including a few Roman temples, etc. untouched. A plus for US folks is English is widely spoken.
