Military map Portugal – 1808

Nineteenth-Century Military Topography and Defensive Cartography of Portugal

This exceptional antique military map, titled “Carta Militar das Principais Estradas de Portugal,” delivers an authoritative geographical and tactical survey of the Portuguese mainland and its strategic Spanish borderlands. The detailed folding map layout utilizes intricate hachure engraving techniques to meticulously depict mountainous terrain, rugged ridges, and major river valley systems that historically served as natural defensive barriers during regional European conflicts.

Historical Transport Infrastructure and Sovereign Heraldic Cartouche

The archival engraving documents the primary network of historical roads, transit corridors, and territorial divisions linking provinces such as Trás-os-Montes, Beira Alta, and the Alentejo plains. Anchored by an elegant oval cartouche in the upper right section featuring the sovereign heraldic coat of arms, this rare cartographic print serves as an invaluable primary source for military historians, genealogists, and collectors specializing in Iberian Peninsula history.
