A striking concrete ventilation shaft for the Pfändertunnel set against the Alpine flank near Lochau — shoot bold geometric forms, textures and contrasts between man-made structure and mountain backdrop. Best at golden hour or blue hour for warm side light and long-exposure traffic streaks; night brings moody artificial light. Accessible from Unterlangenfluh 3 with roadside parking; stay clear of traffic, no interior access. Weather: dramatic skies and low clouds add mood; avoid midday flat sun.
