Where the Limagne meets the volcanic uplands

Riom stands on the threshold between the Limagne plain and the first slopes of the Chaîne des Puys. Its position helps explain its long role as a place of exchange, but the old centre is the reason to slow down. INSEE counted 18,820 municipal residents across the commune in 2023; that reference figure took effect on 1 January 2026. Riom is a working town, with homes, shops, cafés and public services still woven into its historic streets.

The municipality describes an ancient settlement that grew around a religious building and the pilgrimage to the relics of Saint Amable. It also reports the old name Ricomagum, interpreted as “rich market,” as a Celtic place-name. This is the city’s account of the name, not proof that every detail of Riom’s earliest history is known. From the thirteenth century, Riom was the administrative capital of the royal lands of Auvergne. Alphonse of Poitiers’ apanage (1241–1271) brought a new urban plan; during Jean de Berry’s tenure (1361–1416), the ducal residence and Sainte-Chapelle were built.

Civic streets and ducal architecture

The Tour de l’Horloge is the most legible civic landmark. Work began in 1391 for the consular bell, and the tower recalls the communal liberties associated with the 1270 charter granted by Alphonse of Poitiers. Its square base supports an octagonal upper stage added around 1530. Today, the city describes an interpretation room, tactile models and a viewing platform inside. Check opening times and access conditions before planning to climb.

Nearby, the Sainte-Chapelle is the surviving fragment in place of Jean de Berry’s residence. Building began in 1395–96, and dendrochronological analysis cited by the municipality dates the timber frame to around 1403. The chapel belongs to the Ministry of Justice and forms part of the Court of Appeal, so visitors should not expect an unrestricted interior visit. The adjoining garden is open to the public. A walk from there can take in Saint-Amable, the historic squares and the commercial streets around rue de l’Horloge and rue du Commerce.

Museums, market and an everyday centre

The Musée Mandet, founded in 1866, occupies two listed townhouses in the centre; the Musée régional d’Auvergne dates from 1969. Their exhibitions and opening schedules change, so consult current municipal information. On Saturday morning, the outdoor market fills several streets of the old centre; the town lists hours of 8:30 a.m. to 12:30 p.m., while the covered food hall also opens that morning. The market makes clear that Riom’s historic core remains a place to shop and meet, not simply a route between monuments.

Riom returned to the French Crown in 1531 and kept its judicial role. A Court of Appeal was established in 1804 on the site of the former ducal palace. The municipality notes that nineteenth-century growth left much of the old centre intact; it became a protected sector in 1967. That continuity gives a short walking loop a strong sense of time: civic freedoms at the tower, princely ambition at the chapel, religious memory at Saint-Amable and commerce at the market.

Getting there from Clermont-Ferrand

Direct trains connect Riom–Châtel-Guyon with Clermont-Ferrand, around 14 kilometres away. The fastest journey shown by SNCF Connect in the timetable checked for 13 October 2026 took about seven minutes. The local tourist office places the station roughly 500 metres from the centre, making a car-free visit practical. Schedules vary by day; check them before travelling and confirm museum and tower access if those are central to your plan.
