The word(s) "fortifications" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Have they not travelled in the earth and seen how was the end of those who were before them? Mightier than these were they in strength-- and in fortifications in the land, but Allah destroyed them for their sins; and there was not for them any defender against Allah.

(2) Have they not then journeyed in the land and seen how was the end of those before them? They were more (in numbers) than these and greater in strength and in fortifications in the land, but what they earned did not avail them.
