San Piero in Campo sits in the hills 3 km inland from Marina di Campo, surrounded by the pink granite outcrops that made this area significant long before tourism arrived. The granite quarried from these hills — called granito dell'Elba — was used to pave the streets of Livorno, to build quays along the Tuscan coast, and to construct structures across northern Italy. The industry is mostly finished now, but the stone is everywhere in the village: in the walls, in the road surfaces, in the carved doorways. The church of San Niccolò has a granite portal with Romanesque carving that is straightforwardly worth examining, one of the better examples of medieval stonework on the island.
Above the village, a short medieval tower stands on a rise. It is not open to climb, but it anchors the skyline of the village and the surrounding streets are quiet enough that wandering them for half an hour is a reasonable use of time. The views from the upper part of the village look south across the bowl of land down to the bay of Marina di Campo, with the beach visible in the distance. San Piero makes a good combined trip with Sant'Ilario in Campo, a few kilometres further up the ridge — the two villages together can be done in a morning, returning to the coast for the afternoon.
