Crevasse City (Alderaan)

Crevasse City was a city on the Core World Alderaan that was the first and largest of the canyon cities. It was built into the walls of a massive canyon, which allowed it to conceal everything from dwellings to heavy industry underground. Due to its unusual structure and scenic landscape, it became a popular tourist destination, and thus, had its own hotels and resorts. The city had no spaceport, and as such had to rely on Aldera's facilities.

Crevasse City, along with all of Alderaan, was destroyed by the Galactic Empire's Death Star, a mobile battle station that was capable of destroying entire planets.
