This fine eighteenth-century copperplate engraving presents a detailed architectural plan of the Dutch fortress at Quilon (Coylan/Kollam) situated along the Malabar Coast of southwestern India. The layout illustrates the geometric bastions, ramparts, and inner quarters, including palm groves, barracks, and administrative structures. Key features within the fort are designated with alphabetical labels, reflecting Dutch military engineering principles adaptively designed for tropical coastal defence. The surrounding maritime setting features sailing ships, local canoes, a compass rose, and a scale measured in Rhineland rods ('Verges, Mesure de Rhynland'). Published as part of the supplementary volumes to Abbé Prévost's monumental Histoire Générale des Voyages, this plan underscores the strategic visual documentation of European colonial strongholds in Asia during the mid-18th century. Engraved with high precision, the print retains crisp line work delineating both natural geography and fortified structures.
