From the village of Andagna you drive along a narrow but paved road and reach the locality of Drego. Very beautiful views, spring blooms of scented lavender, an ideal place to observe chamois, wild boars and even the Gallo Forcello, thick hazelnut groves and mountain prairies.
The remains of coarse stone walls and the recovery of a coin belonging to the Emperor Julian confirms the presence of an ancient fortress, the Fortress of Drego. It was built during the Iron Age on the spur of the Rock of Drego (1,080m), in a panoramic and strategic position. Later it was occupied by the Romans.
Following the provincial road, it is possible to reach Passo Teglia (1387 m.).
From the top of the pass take the trail that leads across the beech forest in the Rezzo Woodsto the Passo della Mezzaluna.
Between Passo Teglia and Passo della Mezzaluna, along the "Via Marenca" of ancient origin and frequentation, there is the "Ciotto" of San Lorenzo.
Here we can admire an altar boulder, probably used for animal sacrifices, with a cupel and its drainage channel.
The boulder is situated on the edge of a depression in the ground, seat of a small lake, in the last spot lighted by the sun before sunset.
Nearby there is an ancient pastoral settlement under the rock, carved out of a mass of boulders adapted as shelters.
At the highest point of this small valley (Passo delle Porte), from which it is possible to observe the sea, a thick stone in the ground marks a meeting place of great importance.
The menhir is about two metres high, 60 cm wide and 10 cm thick, and it is now inclined on one side.
Even if it is not possible to attribute an age to it, it is clearly a testimony of the pastoral world, which reflects patterns of life and thought that have remained unchanged over the centuries. The analogy (moon and stars) of the names of the places is curious: Mezzaluna (Crescent Moon) and St. Lawrence, that night (10th August) is the night of shooting stars.
Going through the village of Andagna and following the road that leads to Passo Teglia, just before the little St. Bridget's Churchsituated at about 900 metres above sea level, we can see these drinking troughs.
The drinking troughs, “beveaggi" in Ligurian dialect, look like a row of fountains and drinking troughs for horses and soldiers. Used during the wars, these drinking troughs are still intact and clean, even though water no longer passes through their pipes. Built in cement, they are all the same except for the first and the last, which are smaller and more rounded than the other long and rectangular ones.
