Returning from Chun-nan, Sonic and Chip used the key fragments to access the perimeters of the Gaia Temple.

Some time later, the duo returned during daytime and found the second key fragment. Starting out at night, Sonic and Chip found the first key fragment. Having learned that one of the Gaia Temples is located in Spagonia from Professor Pickle, Sonic and Chip came to Rooftop Run to find the key fragments to unlock the gate to the Gaia Temple. In the nighttime acts, Rooftop Top run is overcast by a starry night sky and is lit by the building lights and streetlights. In the daytime acts, Rooftop Run is brightly lit up by the sun and has a partially clouded sky. Noticeable structures in Rooftop Run include a large clock tower, which is presumably based on Big Ben, and aqueducts that tower over the town. On the Wii/PlayStation 2 version of Sonic Unleashed, Rooftop Run also include some water canals and park areas. There are as well hanging plants growing on the buildings. Various shops and restaurants appear at the foot of the regular buildings, while bushes and trees are planted along the streets. The paths in Rooftop Run are cobblestone-laid streets and alleys that run between the buildings, forming a network of paths. The buildings here are built closely together, making the stage tightly packed with structures. These structures are likely based off the real-life buildings in Italy, Spain, France, and the city of Siena. Structures in Rooftop Run include various buildings like apartments, shops and cathedrals, all of which have orange-tiled roofs. Overall, the stage reflects Spagonia's status as an art capital. The stage takes place inside and around Spagonia, a large urban area encircled by a green mountain region, with the urbanized areas stretching up the mountainsides and to the city limits which are marked by large walls.

Rooftop Run's setting is based on various locations in Western Europe.
