The Castle
..... into the city, around which a high wall runs, a beautiful harbor lies on either side of the city, and the entrance is narrow....
Entrance to the city
No-one lives in the old city located on a penninsula anymore. Its only entrance is by bridge, after which it's fairly easy to locate the palace of king Alkinoƶs.
The description of the castle that NausikaƤ gives is still pretty accurate, although it has been rebuilt and changed a lot since her time.
