From the motorway, after the pay toll Lisert-Monfalcone, go straight on for about 18 km and – just passed the tunnel – exit from the freeway at Prosecco/Trieste centre. Go ahead for about 150 mt and turn right in direction Trieste, and then at the crossway turn right again in direction Opicina/Trieste centre. Go straight on for about 4 km to the roundabout with the traffic lights, located just after an Esso gas station. Turn again right at the traffic lights and then, after about 400 mt, at the first bend, go down Via Bonomea. After 500 mt you will reach SISSA Main Entrance.
Please disregard the road sign no thoroughfare: SISSA is located before the access ban. Thus, ignore your satellite navigator, which would advise you for a much longer road trip.
Parking out of the garage is not allowed. You can get to the garage ringing and announcing yourself to "Presidio Tecnico".
