The Holy Kaaba is the most pure architecture known to humanity throughout the length and breadth of time, and the most wonderful view in history in terms of prestige and dignity. The Holy Kaaba consists of buildings and small parts, each of which has its own name. Among those parts is the gutter of the Holy Kaaba. The gutter is the part fixed to the roof of the Kaaba on the northern side, between  the Syrian and Iraqi corners, extending towards al-Hijr, and draining the water collected on the roof of the Kaaba when rain falls or washing the surface to the Hijr of the Kaaba. Since its presence, in the building of Quraysh until the Saudi era, it passed with the attention of Muslim rulers, enabled by Allah to serve His Sacred House through the ages, through repairs at times, restoration at other times, and replacement and change in some cases whenever the need arises. This research is concerned with tracking the historical and cultural development of the gutter of the Kaaba in the Saudi era, and demonstrating the Saudi leadership’s preservation of its restoration, repair, and change, relying on the inductive, analytical, historical approach, through documents of the Mamluk era, a group of sources, and ancient and modern references.

The research reached some results out of which are; the term gutter was mentioned in documents of the Mamluk era with the words “Mīzāb” or “Mīzrāb” to denote, in the same sense referred to, the channel placed in the floor of roofs and protrudes from the building wall to drain rainwater; it is one of the most important works of the Custodian of the Two Holy Mosques, King Fahd - May Allah have mercy on him - during the comprehensive restoration of the Holy Kaaba. He replaced its old gutter installed during the reign of the Ottoman Sultan Abdul Majeed I in 1276H / 1860G, with a new gutter of the same sizes. In addition, so as to increase the strength and durability of the gutter, the same quality of wood used in roofing the roof of the Holy Kaaba and its three inner columns during its comprehensive restoration was chosen, which is teak wood.
