20th century BCE – 18th century BCE
Buhen, Sudan
Buhen Temple is cited as an example of the deterioration of sandstone monuments through salt migration. Soluble salts from saline soil can move into the stone by capillary action and crystallize near or beneath the surface, causing flaking and disintegration, particularly at the lower parts of columns.

The Story
Buhen Temple appears in the passage as a concrete example of the damage caused by soluble salts in African stone monuments. Saline soil supplies the salts, while water or moisture enables them to migrate into the stone through capillary action. As conditions become dry, the salts move toward the outer surface and may crystallize within or beneath it.
This crystallization can force the stone surface to flake away and disintegrate. The effects are especially visible at the lower parts of walls and columns, where the monument meets saline soil. The passage specifically points to the columns of Buhen Temple as an illustration of this process, linking the site’s condition to the interaction between soil chemistry, moisture, and evaporation.
The recommended response was preventive rather than reliant on a single consolidant. Periodic desalination, efficient drainage, and insulation between the monument and salty soil were presented as ways to reduce salt migration. These measures place Buhen within a wider conservation problem affecting archaeological stone structures across Africa.
