This Russian map, published in 1835, depicts the region surrounding Nicomedia (modern-day İzmit, Turkey), a historically significant city located near the eastern end of the Sea of Marmara. The title notes that the map was compiled from various surveys and information provided by the Ottoman government. The map was engraved under the auspices of the Военно-Топографическомъ Депо (Russian Military Topographic Department).
The map encompasses a portion of northwestern Anatolia, detailing the rugged terrain and waterways characteristic of the region. Starting with the contiguous coastline of the Black Sea, the Sea of Marmara is shown at the center left, with Lake Sapanca to the east and Lake İznik (İznik Gölü) below.
Nicomedia, an ancient city with a storied past as the capital of the eastern Roman Empire under Diocletian, is marked as a key urban center on the map. Surrounding villages and settlements are labeled, reflecting the local administrative and cultural geography of the time. Roads and pathways connecting these settlements to Nicomedia and other regions are marked, emphasizing their strategic importance. The Black Sea coast is visible in the northern section, situating the region within a broader geographic context.
