«We forge this city in the heat of twin suns, in memory of our forefathers, in honor of our living clans, and in hope for our children yet unborn.»
―Historical marker in Mos Espa (translated from Rodese)[src]
Mos Espa was a spaceport on Tatooine. It was the home of Anakin and Shmi Skywalker and also held the famous Mos Espa Grand Arena, at which the annual Boonta Eve Classic podrace was held, and the location of Watto's shop.
Mos Espa was an expansive spaceport and rested near the Dune Sea. It consisted of the dome-roofed, adobe buildings found in cities across Tatooine, and was said to appear as a great, twisting snake, hunkered down to escape the heat. Most residents either were involved in crime business with the Hutts or were poor shopkeepers and moisture farmers trying to eke out a living in the inhospitable desert. The biggest retail business in Mos Espa seems to have been junk-dealing, and even small dealers like Watto the Toydarian seemed to rake in a substantial amount of money, albeit sometimes unscrupulously. Locals who spoke Huttese did so with a distinct accent. The other major activity in Mos Espa was gambling on the podraces held in the nearby Grand Arena. The podrace that set Anakin Skywalker free from slavery was held at Mos Espa. Jabba the Hutt may have had some sort of seasonal residence in the city.
