I don't know where she is being built, but our friend Tero in Finland keeps us posted as to progress when a ship is being built there. All I have seen to this point is artist's renderings. You might do a an internet "search" and see what pops up.
Also al lot of information on the ship at http://messages.cruiscritic.com/2/OpenTopic
then scroll down to cruise discussion topics, then click on cruise news, the scroll down to Carnival conquest to make big first impression posted on 08-3-02 and click on it.
