Around 'The Living Legend', L'Aleval, one can find the Kernwerk comprising of 3 SKs for HQ and 2 SKs for telecommunications. Both built on two floors. Only the Communication bunker near 'Le Pissot' and the HQ bunker opposite 'Oaklands' are clearly visible. The other ones are integrated in new buildings. The Kernwerk was defended from the air by three 3.7 cm Flak 41 guns of which two concrete pillars behind the Greenhill hotel survive.
