Laon
A medieval town on a ridge above the Picardy plain, with a Gothic cathedral whose towers are guarded by sixteen stone oxen.
Why go
Laon is what Paris was before it became Paris: a Carolingian royal seat, a cathedral that rivals Notre-Dame, and lanes that have barely been touched. The upper town sits on a long limestone ridge about a hundred metres above flat farmland, so every street seems to end in sky. You can walk the whole ramparts circuit in an afternoon without a single queue, and on misty mornings the cathedral floats above the fields like a ship.
History
A hill that stands alone in a flat landscape is a gift to anyone who needs to hold ground, and Laon has been fortified since antiquity. In the tenth century it became the last stronghold of the Carolingian kings: Louis IV d’Outremer, Lothair and Louis V ruled from here when their power had shrunk to little more than this ridge and its surroundings.
The dynasty ended on this hill. After Hugh Capet was chosen king in 987, the Carolingian claimant Charles of Lorraine held Laon against him, until in 991 the town’s bishop, Adalbero (also called Ascelin), delivered Charles to his rival. A royal line that had begun with Charlemagne’s family ended with a betrayal at Laon.
In the early twelfth century the townspeople formed a commune. When Bishop Gaudry went back on the agreement in 1112, the town rose and killed him; the monk Guibert de Nogent, who knew the town, wrote the vivid account, in which the bishop is dragged from a barrel in which he had hidden. Louis VI granted Laon a communal charter in 1128.
The calm that followed paid for the cathedral. Built from around the 1160s and largely finished in the 1230s, Notre-Dame de Laon became a model for early Gothic builders; the architect Villard de Honnecourt drew one of its towers. It lost its bishop at the Revolution and became a parish church. In March 1814 Blücher used the hill to beat back Napoleon, and from 1989 to 2016 a small automatic train, the Poma 2000, climbed the slope from the station.
What to see
Notre-Dame de Laon cathedral
One of the first great Gothic cathedrals, bright inside, with a four-storey nave elevation and a square east end rather than the usual rounded apse. Look up at the western towers: sixteen life-size oxen lean out of the top arcades, a tribute to the animals that hauled the stone up the hill. Guided climbs of a tower give the best view over the plain.
Ramparts and town gates
Kilometres of walls still ring the upper town, with three medieval gates: the Porte d’Ardon, the Porte des Chenizelles and the Porte de Soissons. Following the promenades along the top gives a running view of the plain on one side and the old houses on the other. The Cuve Saint-Vincent, a green valley cut into the hill, is a surprise in the middle.
Templars’ chapel
A small octagonal Romanesque chapel from the twelfth century, built for the Knights Templar and used as a funerary chapel. It stands in the garden of the town’s art and archaeology museum, a quiet corner that most visitors walk past. The octagonal plan echoes the order’s taste for centrally planned churches.
Saint-Martin abbey church
At the western end of the ridge, a large twelfth-century church of the Premonstratensian canons, the order Norbert of Xanten founded in 1120 at Prémontré, in the forest just west of Laon. Its plain, sturdy Gothic is a good counterpoint to the cathedral’s richness, and the walk there along the ridge is half the pleasure.
Underground Laon
The hill is hollow in places: for centuries the town quarried its building stone from beneath its own streets, and the galleries were later used as cellars and shelters. Guided visits run by the tourist office take you down into them, a cool, strange counterpart to the airy upper town.

Timeline
- 991 Bishop Adalbero hands Charles of Lorraine, the last Carolingian claimant, to Hugh Capet
- 1112 Communal uprising; Bishop Gaudry is killed
- 1128 Louis VI grants Laon a communal charter
- c. 1160? Work begins on the present cathedral
- 1814 Battle of Laon, 9-10 March: Blücher holds the hill against Napoleon
- 1840 The cathedral is listed as a historic monument
- 1989 The Poma 2000 automatic shuttle opens between the station and the upper town (closed 2016)
Uncertain or disputed
- The start date of the present cathedral is given variously as 1150, the mid-1150s or around 1160; we say ‘around the 1160s'.
- The length of the ramparts is usually quoted as about 7 km by tourism sources; we have not found a primary measurement, so we do not give a figure.
- The barrel in which Bishop Gaudry hid comes from Guibert de Nogent’s account, written by a contemporary but not an impartial witness.
Crowds: Rarely crowded. Laon is rarely crowded; summer weekends and the European Heritage Days in September bring the most visitors, so a weekday outside those is quietest. (editorial judgement)
