Tri Postal, Performance hall and former sorting office between Lille Flandres and Lille Europe stations, France.

Tri Postal is a former postal sorting office converted into an exhibition and performance venue in the Euralille district, between Lille-Flandres and Lille-Europe stations. The long red brick building has a flat roofline, pale-framed windows, red vertical panels on its lower section, and a square brick chimney tower bearing the word POSTAL in white letters. Inside, three exhibition levels cover 6,000 square metres.

The Tri Postal sorted Lille's mail during the second half of the 20th century, standing between the Lille-Flandres and Lille-Europe stations. Lille 2004, when the city was European Capital of Culture, saved it from scheduled demolition. Renovation brought it up to standards with a reception area, ticket desks, shops, lockers, a bar, toilets and three exhibition floors totalling 6,000 m². It drew 251,000 visitors that year.

The building's name comes from its postal sorting past, and its programme has kept a strong photographic thread: the Transphotographiques festival has been held here since 2001. Since 2018 it also hosts the Series Mania television festival village, alongside electronic music events such as the NAME festival.

The building stands between Lille-Flandres and Lille-Europe stations in the Euralille district, on Avenue Willy Brandt. The photo shows a white sign with a blue P reading "Mairie" and a blue sign on the facade reading "Parking" and "Mairie / Grand Place", so drivers can head for that car park. The three exhibition levels total 6,000 m² and are reached through a reception area with ticket desks, a shop, lockers, a bar and toilets.

The red brick chimney tower at the right end carries white vertical letters spelling POSTAL, a remnant of the building's mail-sorting past. Below, a blue sign on a mid-facade column points to the Mairie and Grand Place, while a white sign with a blue P marks the Mairie parking.
