Narni
Italy's geographical centre and the etymological 'Narnia' — a 17,900-resident hilltop town on a travertine outcrop above the Nera valley, with the Rocca Albornoz papal fortress, a 30m Roman arch of the Ponte d'Augusto, a hidden underground complex containing a 13th-c Inquisition cell with original prisoner graffiti, and the documented Latin name (Narnia) that C.S. Lewis lifted for his fictional kingdom.
Known for

The festa: Giovenale di Narni, 3 May
Why come
Narni is here for three things at once. First, geography: the Sasso di Narni at the foot of the old town is the documented geographical centre of Italy (calculated by the Istituto Geografico Militare in 1900 — the marker is on the side of the SS3 below the centro). Second, etymology: the Roman city was called Narnia (after the Nar river, modern Nera), and when C.
S. Lewis read about it in his Atlas of the Roman Empire as a boy he liked the name and saved it for The Chronicles of Narnia thirty years later — confirmed in his 1963 letters; the comune has leveraged this with the annual 'Le notti di Narnia' summer festival and a small Narnia-themed museum, though Lewis never visited and the resemblance ends with the name. Third, the actual historic city: a medieval-Renaissance hilltop town on a travertine outcrop 240m above the Nera valley, with the Rocca Albornoz (Cardinal Albornoz's 1370 papal fortress on the high point, square plan with 4 corner towers, panoramic view across the Nera + Tiber confluence), the Piazza dei Priori (medieval set-piece with the 13th-c Palazzo dei Priori), the Cattedrale di San Giovenale (12th-c Romanesque with a 14th-c Gothic façade), and below the centro the spectacular Ponte d'Augusto (the surviving 30m arch of a 27 BC Roman bridge that originally crossed the Nera height — one of the largest Roman bridge arches anywhere in the empire, painted by Corot in 1826 + Turner in 1819).
And underneath all of that, accessed via the deceptively normal-looking Chiesa di San Domenico, is the Narni Sotterranea — a hidden 13th-c Inquisition complex (church + cells + torture chamber) rediscovered by accident in 1979 by local cavers, with original prisoner graffiti scratched into the cell walls including a complete personal-symbology code by a Freemason inmate that took decades to decipher. Visits since 2000 are by guided tour only. The Corsa all'Anello (Race of the Ring, second Sunday of May) is a medieval pageant + horse-jousting competition between the city's three terzieri (Mezule, Fraporta, Santa Maria) — running since 1371 in its current form. The food is Umbrian: strangozzi with truffle (Narni is on the edge of the Valnerina truffle zone), porchetta, pecorino, the local Ciliegiolo + Sangiovese reds.
