About this work
Overview
Upnor Castle, situated on the River Medway near London, is depicted in a pen and iron‑gall ink drawing executed over a graphite underdrawing on laid paper. The work presents a precise, linear representation of the fortress, showing its tower, curtain walls, and the adjacent riverbank with clear delineation of architectural elements.
Subject & Meaning
The drawing serves as a straightforward visual record of the 18th‑century military fortification, emphasizing the structural layout rather than decorative or narrative content. By focusing on the castle’s defensive features, the image reflects contemporary interest in documenting strategic sites for both practical and scholarly purposes.
Technique & Style
Executed with fine pen work and iron‑gall ink, the artist employed dense cross‑hatching to render shadows and surface texture, a method common among military draughtsmen of the period. The underlying graphite sketch provides the initial framework, while the ink lines deliver crisp edges and a sense of depth without the use of colour.
History & Provenance
Created in the 1700s, the drawing is a rare example of a direct, on‑site representation of Upnor Castle from that era. Its survival offers valuable insight into 18th‑century cartographic and architectural recording practices, and it remains an important primary source for scholars studying the castle’s historical appearance.
