Mosque of Sidi el-hal-lui [Saiyyid al-Halawi] (the cake man) the oldest mosque in Tlemcen

The mosque, dedicated to Sidi el-Hal-lui—locally known as 'the cake man'—is a site of local veneration. Dormer’s sketch focuses on its simple minaret rising above a low, flat-roofed prayer hall, underscoring its unadorned, early character. The inclusion of a tree and distant hills situates the building within its natural and urban context, hinting at its role as a quiet anchor in the landscape rather than a monumental religious center.

Executed in pale washes of brown, green, and soft blue, the watercolour employs light, rapid strokes that prioritize atmosphere over precision. The minaret’s cross-like finial and balcony are rendered with minimal definition, while the background structures fade into hazy outlines. This sketch-like approach reflects a topographical tradition common among British travellers, valuing immediacy and record over artistic finish.

Created during Dormer’s travels in North Africa, the sketch is part of a personal archive of architectural studies made in 1870. As a British nobleman with an interest in antiquities, Dormer documented sites across Algeria, including Tlemcen. The work likely served as a personal record, later preserved in family collections, offering a rare visual account of the mosque before modern interventions.

In the 1870s, French colonial administration was reshaping urban landscapes in Algeria, yet many historic structures like this mosque remained relatively untouched. Dormer’s sketch captures a moment before widespread restoration, preserving the mosque’s original scale and setting. His depiction aligns with European travellers’ interest in documenting Islamic architecture as a vanishing heritage.

Though not widely exhibited, Dormer’s watercolour contributes to a small corpus of 19th-century visual records of Tlemcen’s early Islamic architecture. Its simplicity offers insight into how foreign observers perceived local religious sites—not as grand monuments, but as humble, integrated elements of daily life. The sketch remains a quiet testament to the mosque’s enduring, unassuming presence.
