The Cupulo della Cielo, sits on a medium sized island...interlinked by smaller ones. As fit, it has a clear bridge to the main island. This dome though, is easily the biggest of all. It would be more safe to call this a hangar, simply their to hold not only the Maester's air ships, but cargo and other ships. It's also used to create more airships, another thing the Yellow Horizon pride in...their vast number and creation of airships Avial inventions are thought up here as well.

It is of course also used as a main state of entrance.
