Leucera was excluded. Other theories, perhaps legendary, trace etymology back to the Greek therm leukos (white), probably because of the white limestone rocks that can be found in Lecco; from the Latin lucus (forest) and/or lacus (lake). Other theories report a derivation from the Old Indian lokas (country) or Lithuanian laukas (open field). However, the existence of the city was first documented in 845 named Leuco. History Celtic and Roman periods In 1988 excavations of the Civic Museums of Lecco led to the discovery of a village of the Culture of Golasecca (first Iron Age) at the Rocca di Chiuso. The settlement of the Golasecchiani Celts in the area precedes the arrival of the Celts by more than 4 centuries. In 2005 other excavations of the Civic Museums of Lecco and the University of Bergamo unearthed the oldest metallurgical production site in the entire Alpine arc (2nd century B.C. – 1st century B.C.) at piani d'Erna. The Middle Ages As the nodal point of several streets that put Lombardy in communication with the territories of Oltralpe, the region becomes the scene of clashes and decisive battles. The fortified system of Lecco (Castrum Leuci) became the seat, with the Carolingian, of an important Committee entrusted to the Attonid family. In 960 Lecco was submitted to the lordship of the Archbishop of Milan. Throughout the Middle Ages and the Modern Age, the name of Lecco did not indicate an inhabited center but included the whole area between the lake and Valsassina. Lecco was a polycentric settlement, in which the various districts were closely interdependent, each with functional and economic specialization. The Municipal and Viscount period In 1117 a ten-year war broke out pitting many villages of the lakes of Como and Lugano against Milan, of which Lecco was an ally. The inhabitants of Lecco took part in the battle and in March 1125 Como had to capitulate and the victors set it on fire. Later Lecco became involved in the struggles between the powerful Milanese families Visconti and Torriani (the owners of the Valsassina territories). In 1296 the struggles led Matthew I Visconti to destroy the village giving orders that it would never rise again. Despite the destruction, Lecco was rebuilt and reconquered by Azzone Visconti. Throughout the period the community of Lecco, which included the entire current municipal territory, evolved as a free municipality with its statutes and, until 1757, was
