Gypsum plastering (Jass Al-Liyasah)

Gypsum plastering (Jass Al-Liyasah) represents the envelope of the space and its serene face in Al-Ahsa architecture. Its traditional white color grants the walls purity and simplicity, gently reflecting sunlight to mitigate the climate's heat. The plastering was executed by skilled artisans in meticulous layers that protect and beautify the structure without affectation, becoming a defining visual hallmark of both mosques and homes alike.
