We continue on to San Giovanni to admire the frescoes painted by the Master of Roccaverano and see, probably, the last medieval cemetery in the Langa. Just enough time to take a look at the colourful sculptures of the Quarelli Park and you are already descending through a semi-mountainous landscape of crumbling gullies until you reach the ridge of Mombaldone, the only Astigiano village in this valley and the archetype of all medieval villages with its distinctive city gate, stone houses gathered around a single street and the Del Carretto Palace (the castle is no longer there).
Next, we go down to the Excelsior, the landing strip built by the partisans for the British pilots, a story which is told in the beautiful museum of Vesime, our next stop. We have crossed the Bormida and the left bank is definitely steeper, but the climb from the Town Hall up to the romantic ruins of the castle will pay off. Now we go back to Roccaverano on the main road. The two stops along the ridge are San Giorgio Scarampi with its tower and Olmo Gentile (with a tower too) which actually look like two paintings rather than two villages.
