Castle d'Ischia 

Ludwig von Hofmann's "Castle d'Ischia" is a pencil drawing that portrays a serene coastal scene. The artwork features a distant view of a fortified castle perched atop a rocky hill overlooking a calm sea. A lone figure stands on the shore, looking out towards the castle, adding a sense of solitude to the composition. The simple yet effective use of shading creates a sense of depth and atmosphere, highlighting the vastness of the seascape.
