Wikipedia uses "Locale", capitalized as a German noun but otherwise unchanged. It seems to resonate with how the word was originally introduced by John Isbell:
"an inspired choice, which conveyed all the right overtones about the spatial nature of these objects without causing their algebraic underpinnings to obtrude, and which at the same time was easily capable of all the necessary inflections".
