It is known as the Napoleonic street because, according to legend, it was built by Napoleon's troops. The road winds through five kilometers of the Carsian high plain to the villages of Opicina and Prosecco. This walk is well loved by the people of Trieste, and especially popular on Sundays in the spring and autumn. People also come here to run and climb on the rocky outcrops which are on either side of the path. When you are at Opicina, before beginning the walk, have a look towards the sky and admire the white obelisk which was erected by Trieste's Merchant Corp in 1830 in honor of the visit of the Austrian Emperor Franz I. As you set off, the path is very easy to follow (in spite of the fact that it was originally a medieval track which made its way though an oak wood. The wood has now disappeared.) and the distance in altitude between Opicina and Prosecco is only around 100 meters. It is a perfect way to spend a morning immersed in nature, surrounded by red sumac, sage and other beautiful countryside with wonderful views over the sea. The area was put into order by the Giulian Alpine society and dedicated to the climber Nicolo Cobolli in 1935. It is sheltered from the bora and is often bathed in the sun making it a sunny island in the winter months. After you have walked leisurely for around an hour you will get near to San Nazario which is a typical village of Carso. You can go from here to the charming sanctuary at Monte Grisa.
