Mos Eisley was located in a valley somewhere to the southeast of the Jundland Wastes and roughly 80 kilometers north of Anchorhead, near the desert palace of Jabba the Hutt.
From a distance, the spaceport appeared as a haphazard collage of low-grade duracrete, stone, and plastoid structures that spread outward from a central power and water distribution plant. The city lacked a main landing facility; therefore it relied on 362 individual hangars. By order of the Empire, all of these hangars were equipped with time-lock devices. Illegally parked vessels were not an uncommon sight.
The town was really larger than it looked, as a good portion of it lay underground. In fact, it had a population of around 40 to 60 thousand people, varying seasonally.
Streets in the city included Corporation Road, Curved Street, Outer Curved Street, Straight Street, Spacers Row, Paradise Road, Dune Street, and Kerner Plaza. Many citizens rode rontos, dewbacks, and other beasts of burden.
The streets of Mos Eisley.
Mos Eisley was divided into the "New Quarter" and the "Old Quarter". The Old Quarter was originally wheel-shaped and contained a thriving marketplace. Jabba the Hutt also maintained a residence there, known as the Desilijic Complex, since it was difficult to make business from his palace. The New Quarter was more tourist-friendly and was a merchant district where tourists could relax (though there was still much crime). Chalmun's Spaceport Cantina served as the hub of the newer quarter. Each quarter had individual neighborhoods, such as the rough-and-tumble Tar Mass area.
During the Galactic Civil War, the Empire established a small garrison in Mos Eisley, although this did not help with the city's massive crime rates. The base was located near the cantina and whenever an expansion was required, the Empire would simply level surrounding buildings. To support the constant flow of spacers, Mos Eisley featured a large number of hotels, casinos, and cantinas.
The shops district was close to a hangar, the markets, a warehouse, and a housing complex.
