In Voyage en Sardaigne (1857) La Marmora hypothesised that the name derived from the fact that it arose in an expanse of a once-eruptive mouth. Pozzomaggiore is at the heart of a volcanic area with basaltic and andesitic rocks, with ‘truncated’ hills and low plateaus covered with Mediterranean scrub and dotted with cork oaks and holm oaks contorted by mistral winds. The village of 2,700 inhabitants is part of Meilogu, the ‘heart’ of Logudoro, separated from Planargia and Montiferru by the Riu Mannu, where the Oinu bridge is preserved, standing since the 3rd century AD. The historic centre is overlooked by stately homes, including Palazzo Parpaglia, and the parish church of San Giorgio Megalo built in late Gothic style in the mid-16th century. The interior is divided into five bays, with the last - the capilla mayor, featuring a star vault and pendulous jewel. The façade has buttresses that ‘draw’ a scenic backdrop, exalted by a staircase. The portal reinvokes that of San Pietro ‘extra muros’ in Bosa. The patron saint is celebrated at the end of April with an ardia that is held in Piazza Maggiore.
