This fine early 18th-century hand-colored copperplate engraving presents a dramatic bird's-eye panorama and inset ground plan of the fortified city of Casale Monferrato (Casal dit de St. Vas) situated along the Po River in northwestern Italy. Published in Amsterdam by Pierre Mortier, the view highlights the extensive star-fort fortifications, defensive walls, bastions, and prominent citadel that rendered the city a key strategic stronghold during European military conflicts of the period. The upper visual composition captures the town from an elevated perspective, detailing the dense urban fabric, church spires, surrounding countryside, rolling hills, and the winding course of the Po River. In the foreground, figures in contemporary travelers attire on horseback and foot animate the rural landscape. In the lower right corner, a detailed inset map illustrates the precise military architecture of the hexagonal citadel and town ramparts alongside the river branches.
