Grand Portet

Grand Portet opened in 1972 in Portet-sur-Garonne, a Toulouse suburb, anchored by a Carrefour hypermarket that, at roughly 24,400 sqm across 2.5 hectares, briefly stood as Carrefour’s largest hypermarket in Europe until 2008. That year, Carrefour scaled the store back by around 6,000 sqm amid declining footfall while testing new retail concepts at the location, a reduction that brought the property closer to its current roughly 18,000 sqm scale.

The property has long served as a testing ground for Carrefour’s own format experiments, with the group using the Portet site to trial store concepts before wider rollout. Carrefour anchors grocery, with a jewelry and gifting cluster including Histoire d’Or rounding out the broader specialty tenant mix across the property’s roughly 110 stores.

Klépierre now operates the center, marking its 40th anniversary with a renovation that refreshed the property’s format and tenant mix. Located 20 minutes from central Toulouse, France’s fourth-largest city, the property is served by the A64 motorway, several bus lines and a nearby train station.

That trajectory, from Europe’s largest Carrefour hypermarket to a scaled-back but still substantial regional center under specialist mall operator Klépierre, illustrates how even flagship-scale single-retailer developments from the 1970s have had to shrink and diversify their tenant base as shopping formats evolved over five decades.
