Waypoint introductions and full write-ups
1. Evaporiti di San Leo
San Leo stands on a limestone block that rises sheer out of the Marecchia valley, and from a distance it looks like a fortress that nobody could possibly have captured. The ground under it tells a longer and stranger story. The evaporite rocks in this area, gypsum and associated salts, were laid down around six million years ago, when the Mediterranean nearly dried out in what geologists call the Messinian salinity crisis. Seawater evaporated, minerals crystallised, and the beds you see in the cuttings are the leftovers of that event.

Planning note
Evaporiti di San Leo is where the day begins. Next is Basilica of St. Apollinare in Classe, 69 km on.
2. Basilica of St. Apollinare in Classe
For centuries the sea reached this field. Classe was the port of Ravenna, a harbour built by Augustus to station the Roman Adriatic fleet, and merchants, sailors and soldiers filled its quays until the river silt choked the channels and the coast crept east. Today the port is farmland, the sea is five kilometres off, and the great church of Sant'Apollinare stands alone among the fields, a tall brick basilica with a round bell tower, rising from the plain like a ship stranded on a sandbank. It was consecrated in 549, in the time of Justinian, and stands over the tomb of the first bishop of Ravenna, Apollinaris, who is said to have been a disciple of Saint Peter. UNESCO listed the early Christian monuments of Ravenna in 1996.

Basilica of St. Apollinare in Classe comes up about 75 km into the recorded legs. Next is Vena del Gesso Romagnola - M.te Casino, 69 km on.
3. Vena del Gesso Romagnola - M.te Casino
Crystals the size of a hand catch the sun along the Vena del Gesso, a ridge of selenite gypsum that runs for some twenty-five kilometres across the hills of Romagna, from the Sillaro valley to the Lamone. The rock formed millions of years ago when the Mediterranean dried up and its salts were deposited, and it has since been carved by water into caves, sinkholes and blind valleys. In 2023, UNESCO listed the evaporite karst and caves of the northern Apennines, and the Vena del Gesso is the heart of it. Monte Casino is one of the peaks on the ridge, near Borgo Tossignano and Casola Valsenio.
