The town is characteristic of the bastides in the area - central village square with the town hall a main feature, with the village shops clustered along the four sides of the square. Wide arched pavements allow dining out of doors in the summer, when music is piped around the square. The town convent (now the town hall and cinema) and church steeples are lit up at night. The town is also home to many restaurants, including "Le Monde A L'Envers" (The World Upside Down), run by London chef Victoria Heath.
A great emphasis is placed on jazz in the town, which is taught as a regular subject in local schools. The town itself is known for its annual Jazz in Marciac festival, held for a fortnight in August. A marquee ("le chapiteau") capable of seating 6,000 is erected on the rugby field, with concerts hosted there every night for the duration of the festival, and free music from 1100 till 2000 every day. Stalls selling a variety of related and non-related merchandise are erected in and around the centre of the village square, where free concerts are given during the day. Other musical events take place around the town at the same time, such as the "Atelier de Jazz".
