Saint-Roch is the inner centre of Mont-de-Marsan. The geographic check places within it place Saint-Roch, place du Général-Leclerc and the town hall, rue Léon-Gambetta, the Plumaçon bullring and the Lacataye keep. It is the core of the chartered town founded in the twelfth century on the spur above the meeting of the rivers.
What remains of it are the Romanesque houses of rue Lacataye, among the oldest surviving civil houses in France, two of which, joined together and built into the town wall, form the keep that houses the Despiau-Wlérick museum. Around them, the fabric grew denser in the nineteenth century with the boulevards that replaced the ramparts: rue Pierre-Lisse, boulevard de la Brigade-Carnot, avenue des Martyrs-de-la-Résistance, rue Saint-Pierre and rue Frédéric-Bastiat.
On the market, Saint-Roch stands at 2 147 €/m², barely above the town average, on thirty-seven apartment sales a year. That is the particularity of Mont-de-Marsan: unlike most French towns, the historic centre is not the most expensive area. It gains 10 % over five years and 4,9 % over twelve months.
Saint-Roch attracts buyers who want everything within walking distance: shops, the market, schools, public offices, the bullring and the riverside. Investors target small units, carried by steady rental demand. The stock mixes older buildings, often without a lift, and more recent blocks along the boulevards. Parking is the weak point of the area, and it weighs on the price gaps from one building to the next, from 1 846 to 2 419 €/m².

No, and that is a particularity of the commune. Saint-Roch, which holds the inner centre, sits at 2 147 €/m², barely above the town average and below Beillet, Crouste and Saint-Jean-d'Août. In Mont-de-Marsan, being central creates no price premium: the gap between the first and the last district is only 18 %.
The district mixes older buildings from the medieval core, often without a lift, and blocks of flats along the nineteenth-century boulevards. The band runs from 1 846 to 2 419 €/m². Lifts and parking, both scarce in the older fabric, explain much of that spread.
