The historic centre of Casperia is a typical example of a medieval village: the streets are in concentric circles which get smaller and smaller as you go up the hill to the top where the piazza of San Giovanni Battista is with its church and its monumental bell-tower. The walls of the village date back to 1282 and are only broken by two gates: Porta Romana, to the west and Porta Reatina, to the north-east, above which is the extraordinary six hour clock. Of the original walls, from the 11th Century, the only part that is still visible is the arch in via Garibaldi – testimony to the fortress of Aspra which is what the village was called until 1946. Since 2004 Casperia has waved the Orange flag of the Italian Touring Club – a tourist and environmental quality mark – because: «this place distinguishes itself for the homogeneity of the old centre. The care taken in cleaning and generally looking after the village are excellent. It is worth noting the addition of many tourist services in the typical old buildings».
