A visitor examines a ruined lakeside fortress, noting its ramparts, masonry, roofless barracks, and the weeds and trees that have grown within. He contrasts a young engineer’s technical reading of ditches and angles with his own poetic, historical imaginings of past garrisons and campaigns. In a series of reveries he reconstructs scenes of soldiers, allied warriors, music, and camp life, then watches those images fade back into present tranquility. The piece meditates on the passage from war to peace, the coexistence of material ruin and memory, and nature’s slow reclamation of human works.
