Palazzo San Giorgio
it's nowadays the headquarters of something to do with the harbour - something i can't translate (consorzio del porto, if you speak italian). There used to be a prison in there, many centuries ago, and someone dictated (wrote?) a 'guide-book' about Asia - quite some years before Marco Polo. Who and when exactly, I'll try and find out soon.

Within a few metres at Porto Antico is the "Aquarium" and the "Galata Museo del mare". Our favorit ship was "Neptun". The boat was built for Roman Polanskis movie "pirates"
