Yemeni Madfan: Underground Grain Store
A madfan is a covered underground grain chamber documented in Yemen, excavated in rock or firm earth. Sources do not establish one universal shape, locality or performance.

Mandi pit oven
Mandi ovens are ground-built pits for cooking a regional dish. A 2024 Seiyun report describes wood-fired pits dug into the earth; Saudi sources describe separate clay or iron restaurant pits and a tannour form.
A regional family of ground-built ovens
Mandi pit ovens are built into the ground for a dish associated with Yemen and Saudi Arabia. The available accounts describe more than one form, so this page keeps regional evidence separate. A 2024 report from Seiyun in Hadramaut describes a firewood oven dug into the earth, preheated before meat is put on a grill and sealed inside. Saudipedia's Saudi account describes circular restaurant pits made from clay or iron, and a tannour with heat-resistant brick walls, steel lids and hanging rods. Those Saudi specifications are not measurements for the Hadrami oven.
The page's linked photograph adds a view of one empty Mandi pit: a circular brick-lined shaft with a dark metal rim and two hanging rods. The Commons file identifies it as a pit built specifically for Mandi, but does not record where it was photographed. It therefore supports the pictured form, not a claim that the same materials or geometry are standard in Seiyun, Hadramaut, or across Saudi Arabia.

Heating and sealing in the Hadrami account
Kurdistan24's correspondent reports from a restaurant in Seiyun where cooks season meat while a team prepares the oven. Firewood heats the underground oven before the meat is placed on a grill. The oven is then sealed tightly, and the observed smoky cooking stage lasts about an hour. The cooked meat is arranged over rice for service. The account does not publish the seasoning proportions, pit depth, wall material, exact sealing method or temperature. It reports one professional preparation, not a universal recipe or a measured construction plan.
The Saudi documentation describes a distinct restaurant setting. Its Mandi page gives a circular clay or iron pit no deeper than 100 cm and 40–50 cm wide, heated with firewood until it becomes embers. It also describes a tannour with heat-resistant brick walls, stainless-steel rods for hanging meat and two steel covers. These details show how one Saudi form is built and equipped; they should not be silently added to the Hadrami report.

What the sources do not establish
The sources establish contemporary use and regional examples, but do not identify the earliest attestation of Mandi ovens. The Saudi dimensions are published for Saudi restaurant pits, not for Yemen; the empty Wikimedia photograph has no locality; and the report from Seiyun does not describe its oven walls or cover. The illustration therefore follows the photographed empty brick-lined pit, while the prose keeps its location unknown and its form distinct from the reported Hadrami installation.
This record documents a structure and its reported use, not instructions to excavate or operate a fire pit. The sources reviewed do not provide ground-stability guidance, fire clearances or food-temperature controls. No such values have been inferred, and the image is editorial art rather than a construction drawing.

History
The inspected evidence documents current practice: a field report from Seiyun in 2024 and Saudi cultural documentation. Neither source establishes when Mandi ovens began.
Site
SettingGround-built ovens used in restaurant cooking; a 2024 report documents a Hadrami restaurant in Seiyun, eastern Yemen.
GroundThe Hadrami report says the firewood ovens are dug into the earth. The Saudi restaurant form is described separately as a circular pit.
ClimateThe consulted sources do not establish a climate requirement for the oven.
FootprintNo dimensions are provided for the Seiyun oven. Saudipedia gives measurements for a separate Saudi restaurant form: no deeper than 100 cm and 40–50 cm wide.
NotesThe measurements belong to the Saudi documentation and must not be transferred to the Hadrami example. This page is not a construction plan.
A build is made where it stands: moving it means building it again.

Risks and precautions
This descriptive record is not a construction or food-safety plan; the inspected sources do not establish excavation, fire-clearance, structural or temperature controls.
Materials
- Earth and pit walls — The Hadrami report describes ovens dug into the earth but does not identify the wall material or lining.
- Firewood — Burned in the pit to preheat the oven.
- Cooking grill or support rods — Meat is placed on a grill in the Hadrami report. Saudipedia describes stainless-steel hanging rods in its Saudi tannour account.
- Oven cover and seal — The Hadrami oven is tightly sealed around the meat. Saudipedia describes tightly sealed lids for Saudi Mandi pits.
- The Hadrami source describes a ground-built firewood oven but does not give a construction drawing, wall material or build dimensions; do not infer these from the separate Saudi examples.
- Preheat the wood-fired oven before loading the meat. In the 2024 Seiyun report, the cooking team prepared the oven while the meat was seasoned.
- Place the meat on a grill or support and close the oven tightly. The report describes a smoky cooking stage of about one hour in the observed restaurant method.
- Remove the cooked meat and serve it over rice in the reported Hadrami presentation. This food-serving practice is separate from the oven's construction.

MandiDescribes Saudi Mandi restaurant pits as circular clay or iron forms, no deeper than 100 cm and 40–50 cm wide, heated with firewood until embers form.
Describes a Mandi tannour with an underground cylindrical pit, heat-resistant brick walls, steel lids and stainless-steel hanging rods.
These measurements and details describe the Saudi examples and are not transferred to the Hadrami oven.

SaudipediaRegional variation · Materials
What Is the Tannour?Describes Saudi tannour forms as circular, historically made from stone clay and fired with wood; modern variants use iron sheets and gas.
Gives a cavity about half a metre in diameter and one metre high for the tannour family; this is not a specification for the Hadrami Mandi oven.
