Map of the city of Cairo (1525)

What makes this map especially interesting is that it does not present Cairo as an abstract name on a route, but as a dense and recognizable city with its own districts, monuments, and sacred geography. Piri Reis includes not only the Nile and the urban core, but also places such as Giza, Bulaq, Old Cairo, and the City of the Dead, giving the viewer a sense of Cairo as a lived and layered metropolis. The unusual south-up orientation reinforces that this is not a modern city plan, but a 16th-century Ottoman way of organizing space according to navigational logic and regional priorities.

Cairo in the Kitab-ı Bahriye

The map of Cairo was created in 1525 as part of Piri Reis’s Kitab-ı Bahriye (Book of Navigation), one of the major achievements of Ottoman cartography. Compiled during the reign of Sultan Süleyman the Magnificent, the work brought together nautical knowledge, geographic description, and visual mapping into a highly sophisticated navigational manual. In this context, Cairo appears not merely as an inland city, but as a strategic and cultural center connected to the Nile and the wider eastern Mediterranean world. The map’s orientation, with south at the top, reflects conventions common in early modern navigation and reminds us that Piri Reis was mapping according to the practical and spatial logic of his own time.

An Ottoman View of a Major Islamic City

By the early 16th century, Cairo was one of the most important cities in the Islamic world, valued for its political, commercial, and religious significance. For the Ottomans, it mattered not only as an urban center but as a place of symbolic and strategic importance within a larger imperial geography. Piri Reis’s decision to include the city in such detail suggests that he understood it as more than a point of passage. Its districts, monuments, and surrounding areas are given enough attention to show that this was a place that had to be known, understood, and situated within Ottoman knowledge of the region.

City, Monument, and Sacred Landscape

One of the strongest features of the map is the way it combines urban and sacred topography. Alongside districts such as Imbaba, Bulaq, Shubra, Giza, and Old Cairo, Piri Reis also marks the City of the Dead, with its tombs and shrines, including that of Imam al-Shafi‘i. The inclusion of the pyramids is equally telling. They appear not simply as ancient structures, but as part of the visual and symbolic identity of the region. The map therefore presents Cairo as a city in which everyday settlement, religious memory, and monumental history coexist. It is this layering that gives the image much of its richness.

Cartography as Knowledge and Power

The Cairo map demonstrates how Ottoman cartography could serve several purposes at once. It was useful as a navigational and geographic aid, but it also recorded political and cultural knowledge. Piri Reis was both an admiral and a cartographer, and his maps often show that double perspective: they are shaped by practical maritime concerns but also by a desire to organize and communicate the world in a broader intellectual sense. In the case of Cairo, that means presenting the city as a major node within the empire’s understanding of land, river, and sacred history.

Ink, Color, and the Craft of Mapping

The map measures approximately 34 x 24 cm (13.4 x 9.4 in.) and is executed in ink and paint on laid paper, a high-quality support commonly used in Ottoman manuscript production and mapmaking. This medium allowed for the clarity and refinement that characterize Piri Reis’s work. Fine lines define waterways, city structures, and significant locations, while color helps separate and emphasize geographic features. The balance between decorative finish and geographic precision reflects the high level of technical and artistic care that went into the Kitab-ı Bahriye as a whole.

Preservation in Baltimore

The original 1525 map of Cairo by Piri Reis is preserved today at the Walters Art Museum in Baltimore. There it remains an important example of early Ottoman cartography and one of the earliest known mapped representations of Cairo, valued not only for its geographic content but also for the historical perspective it offers on how the city was seen, structured, and understood in the early 16th century.
