(ラバナスタ・ダウンタウン, Rabanasuta Dauntaun, lit. Rabanasta Downtown)

Lowtown lies, as its name would suggest, beneath the city streets of Rabanastre. Great pillars standing throughout Lowtown support the soaring edifices above. Prior to the war with Archadia, many merchants used Lowtown as a place to store foodstuffs and wares for sale. With the defeat and occupation by Archadia, many of the former residents of upper Rabanastre were relocated here, leading to its gradual transforming into a residential area. No natural light shines on Lowtown, save where there are passages to the streets above, making it perpetually gloomy. Many orphans from the war have adopted Lowtown as their new home.

Old Dalan has his house in Lowtown, and Vaan's friend Kytes can also often be found about. Lowtown has passage to the Garamsythe Waterway. Some rare equipment can be bought at Lowtown's South Sprawl after the events at Giruvegan.

Lowtown is the only area in Rabanastre where the player may find treasures. Unlike treasures in most other locations, Lowtown treasures are stored in urns covered in blue cloth. In the original version, the treasure outside Old Dalan's house is a forbidden chest (labeled in red) that, once claimed, prevents the player from obtaining the Zodiac Spear, the most powerful weapon, in Necrohol of Nabudis.

The other treasures are nothing special, mainly containing Potions. With Diamond Armlet equipped the treasures are mainly Knots of Rust, with the rare treasure being Ether or Hi-Ether.

In the Zodiac versions, the forbidden chest gimmick has been removed, it is safe to open every chest down in the Lowtown. The treasures are mostly typical healing items as in the original version. Diamond Armlets, as is usual for this version, in this location will reveal only Knots of Rusts and Meteorites.
