The following travel options are possible. Due to limited parking capacity we recommend you to use public transport to get to Fraunhofer IOF.

By public transport

If you take the route from north to south you will arrive at the station Jena-Paradiesbahnhof. Please go to the bus stop on Teichgraben (5 minutes into the city) and take the Number 10, 11, or 12. Step off the bus at “Beutenberg Campus” and follow the direction sign to Fraunhofer IOF

If you take the route from west to east, leave the train at Jena-Westbahnhof. After the bridge on the right hand you will see the bus stop Magdelstieg. Use the same lines to Beutenberg-Campus.

By car

Leave the A4 motorway at the exit Jena-Göschwitz, follow the federal highway B88 into town, turn off left toward Winzerla, along Winzerlaer Strasse until the direction sign “Fachhochschule – Beutenberg Campus”. On the left side you will see the Fraunhofer IOF. Use the gateway “Beutenberg Campus Nord” and follow the direction sign.

By plane 

Starting from airport Leipzig/ Halle on the A9 motorway to the south (direction Munich) up to the Hermsdorfer Kreuz. Here you have to change the motorway, follow the A4 motorway westward (direction Frankfurt) and leave it at the exit Jena-Göschwitz, further see car.

Or starting from airport Erfurt on the A4 motorway direction Dresden to exit Jena Göschwitz.


Fraunhofer IOF is located at

Albert-Einstein-Str. 7
07745 Jena

On March 28 we offer our guests, who arrive earlier in Jena, a  pre-program.
