The cycle-pedestrian bridge over the Soča/Isonzo offers a beautiful view of this stretch of the river. Further on, you can see the railway bridge of Solkan, the stone bridge with the largest arch ever built to date.

In the center of San Martino, a small private museum has hosted, since 2007, a permanent exhibition titled "Ricordi della Grande Guerra a San Martino del Carso." The exhibition gathers various artifacts and materials found in San Martino, on Monte San Michele and the surrounding territories. https://www.turismofvg.it/museo-privato-ricordi-della-grande-guerra-a-san-martino-del-carso

Nice passage to cross the Isonzo. Given the very narrow tracks and the constant amount of traffic, I recommend crossing via the pedestrian bridges on the sides.

A city wall, built towards the end of the Middle Ages, which combines all the attributes of fortifications of that time - well worth seeing!
