A small grotto set beneath the Arco Schlösschen near Neuburg an der Donau. Photograph cave textures, dripping-water details, and moody recesses with shafts of light. Best light is late morning to early afternoon for workable brightness; go on weekdays for quiet exploration. Access is mainly on foot from the grounds—check local opening/entry times and bring a flashlight; parking in Neuburg outskirts or near the Schloss area.
