The previous building had a moatlike
light well separating it from the street.
Though defined in terms of the morphology of circumferential, moatlike
depressions, radial fracture systems, and so on, these features commonly contain small volcanic edifices (fields of small shields or domes), small calderas, or lava flows, the latter often apparently fed from elongate vents coincident with the distal parts of radial fractures.
As KC Pau's image, at left, suggests, the wall is ringed by a moatlike
area with volcanic features at both its north and south ends.
He illustrated his account with a drawing of the ruin that accentuated its central tower and set the main building apart by an imaginary; moatlike
arroyo, thereby increasing dramatic and reflective distance.
It also boasts an open courtyard and such intriguing architectural features as winding passages and a moatlike
Sabine, the easternmost one, has an unusual ridge that resembles a thin doughnut extending around the moatlike
edge of its floor.
