## Key facts

- **Region:** Fouta Djallon, Guinea
- **People:** Fulbe (Fula, Peul)
- **Roof:** Conical thatch with veranda eaves
- **Rainfall:** About 1,500-2,500 mm (60-100 in) a year
- **Landmark:** Friday Mosque of Dinguiraye

The Fouta Djallon highlands of central Guinea are home to a distinctive Fulbe (Fula, Peul) building tradition of round earth-walled houses and square mosques covered by large, heavy thatched roofs. The highlands receive roughly 1,500-2,500 mm (60-100 in) of rain a year, most of it between June and September, and its roofs are designed above all to keep that water off unbaked earth walls.

## Houses

Residential buildings are usually circular, with a conical thatched roof over a single round room. Long rafters meet above the centre, run down over the walls and continue past them to rest on a ring of outer posts, forming a shaded veranda all round the house. The result is a very regular cone with wide eaves. There is no ceiling, so the underside of the thatch is visible from inside and may be decorated with horizontal rings of bound thatch. Walls, floors and beds can carry incised and painted geometric decoration.

## Mosques

Fouta Djallon mosques reverse the usual relation between plan and roof. The prayer hall is a square earthen block, but it sits under a great conical or dome-like thatched roof that extends beyond the walls on a ring of stakes. Often cited as the largest and most elaborate example is the Friday Mosque of Dinguiraye, associated with the 19th-century leader El Hadj Umar Tall. Inside, a large central pillar flanked by smaller poles supports an earthen ceiling over the hall; above this, an inverted umbrella of radiating poles springing from the central pillar carries the thatch and stops the long rafters from sagging. The art historian Mark DeLancey describes it as a circular-plan roof centred on the pillar of a square-plan building.

## Why heavy thatch

DeLancey notes that the heavy thatch and wide eaves exist to protect the unbaked earth walls from the rains.

## History

A Fulbe Islamic state was founded in the Fouta Djallon in the early 18th century. Architecture of the region was documented by French colonial writers in the first half of the 20th century and later studied in detail by Labelle Prussin. A *case de couronnement* (coronation house) of the Almamy rulers of Fouta Djallon is on Guinea's tentative list for World Heritage nomination.
