The Old Woman's Wall

The Old Woman's Wall is a wall that encircles the lands of Egypt, running along the edge of the cultivated land, as if it were made as a barrier between the sand and the crops. Ibn Fadl Allah al-Umari walked along it as far as Dandara in Upper Egypt, and saw that it was built of brick, that most of it had been effaced, and that its broken parts outnumbered its connected ones. ²

Al-Umari found in the books of the reports of Egypt that it was built by a woman named Dulluk, and that it reaches as far as the space between al-Arish and Rafah. But he said there is no trace of it there or in the lower parts of Egypt, and its builder is not known for certain. ²
