Atom Cellar:  2 Hours

The town of Haigerloch, located about a 20 minute drive from Bondorf, is home to the secret laboratory where Germany did its nuclear research during World War II.  The short tunnel bored into a cliff face is now the small Atom Cellar (Atomkeller) Museum.  The project was accidentally discovered, and subsequently shutdown, by the Americans.  The displays are in German, but an information booklet in English is available.  30 minutes is sufficient to see the museum.

Haigerloch is on the way to Hohenzollern Castle or the Fossil Museum, so this trip could easily be combined with either of these other itineraries.

Opening Times and Fees:

May-Sep Daily 10:00am-noon & 2:00pm-5:00pm
Mar-Apr & Oct-Nov Sa-Su 10:00am-noon & 2:00pm-5:00pm
Dec-Feb Closed




Take the A81 south in the direction towards Singen.

Take the second exit, labeled Empfingen.  Turn left at the bottom of the exit ramp in the direction to Balingen.

In less that 10km, turn left following signs to Haigerloch.

Once in Haigerloch, there will be small signs directing you to the Atomkeller.  Go straight when the main road makes a sharp right-hand turn.  This road looks more like an alley, but it is in fact a public road that goes steeply down hill.  At the bottom of the hill, turn right.  After a few blocks, there will be a small (but marked) parking lot down a small alley to your right.  The entrance to the museum is a little further down the alley beyond the parking lot.
