Lecce nei Marsi is said to have risen in the Longobard era, after the destruction of the ancient Marso castle during the social war fought by the Italics against the Romans. From the 15th century, Lecce, called Licine (or Lycia) in the Middle Ages, was among the 'castles' of the county of Celano. The village was destroyed by the earthquake of 1915, which marked the definitive departure from the pastoral economy, which was no longer flourishing at the time. The reconstruction of the new urban centre was relocated further downstream, in the Fucense area. The most striking areas are the ruins of Ca' Buccella, Ca' Marino, and the ruins of Sierri. Higher up at 1,300 metres above sea level, at La Guardia, are the remains of the castle and tower of Litium. Several nature trails cross the contiguous area of the Abruzzo, Lazio and Molise National Park, reaching the Macchia locality, the La Guardia beech woods, the Diavolo refuge and the mountainous areas of the neighbouring municipalities of Collelongo and Villavallelonga. Home of Andrea Delitio, whose artistic skills are expressed in the chained Duomo di Atri.
