The Island the Trade Built

A short walk through Nantes' shipowners' island, where 18th-century houses still wear the faces of Atlantic trade, and down to the Loire quay where that trade's human cost is written in glass.

This walk crosses an island that is no longer an island. Between 1926 and 1938, Nantes filled in the two arms of the Loire that had wrapped around the île Feydeau, and the quays that once met water became the pedestrian allées you walk today. What remains is a street of tall 18th-century houses built on the money of Atlantic trade.

You pass the Temple du Goût, the 1753 house of the slave-trading shipowner Guillaume Grou, and the hôtel de la Villestreux, the island's largest residence, before stepping onto the quai de la Fosse, the city's true port front.

The walk ends at the Mémorial de l'abolition de l'esclavage, where 2,000 glass plaques underfoot name the slave ships that sailed from this river, alongside the African trading posts and the Caribbean, American and Indian Ocean ports of sale. It is free, and it makes the cost of those façades plain.

Allée Duguay-Trouin

A former river quay that lost its water in the 1930s.

You're standing on what was once the northern edge of a real island. Until the 1930s, the Loire split around this strip of land, and the water of the bras de la Bourse came right up to these stones. The quay you're on got its concession in 1721, and the wall began to rise in the summer of 1723, work that took nine years. It was laid out as part of the île Feydeau, a brand-new quarter for the city's shipowners and merchants, and the tall houses behind you were their showpieces, every one of them paid for by Atlantic trade.

Jules Verne was born on this island too, at 4 rue Olivier-de-Clisson, where a plaque marks the house. Then the city filled the river arm in, between 1926 and 1938, and when the sand settled the island was land. The quay became an allée, a road with no water to meet. Much of it still carries cars; only the stretch between cours Olivier-de-Clisson and rue Léon-Maître was given over to pedestrians and bikes, its paved quay remade beside a green ditch.

Look at the line of the pavement and the low strip of grass beside it. That is the ghost of the river.

Temple du Goût

0:00

The island's flashiest house, built for a slave-trading shipowner.

This is the most theatrical house on the island, and its name is a joke that stuck. The Temple du Goût, the temple of taste, was built in 1753 by the architect Pierre Rousseau for Guillaume Grou, one of the richest shipowners in Nantes and a man who made much of his fortune in the slave trade. Rousseau gave it the most spectacular façade on the île Feydeau and liked his own work enough to keep an apartment here from 1755. The nickname is said to be the city's, or maybe Rousseau's own.

Look up at the first floor. Above the central windows sit carved faces, the mascarons. One is a woman with garlands of flowers and grapes in her hair; another is a bearded man in a turban, posed like a traveler. These were a merchant's calling card, a nod to the trade that paid for the stone.

The woman with the flower garlands and the turbaned man still watch the allée from the first floor.

Rue Kervégan

0:00

The island's main street, where mascarons tell the trade's story.

You're in the spine of the island now. Rue Kervégan runs the whole length of the île Feydeau, and its name is a small piece of the story. It was renamed in 1817 for Danyel de Kervégan, a merchant, a slave-trading shipowner and a former mayor, who lived and died on this street. The houses were ambitious from the first day, and the ground nearly defeated them.

Raised on sand, several began to settle as soon as the scaffolding came down. It took Pierre Rousseau, the same architect who built the Temple du Goût, to steady the district: around 1755 he introduced timber raft foundations in the Dutch manner, and you can still see the tilt in a few façades. And the street today is as much about dinner as architecture. It is one of the city's restaurant and bar streets: Le Cèdre for Lebanese food, Cascabel and A Cantina for evening crowds, and Royal Indien at number 13.

Look up above the doorways. The carved faces are the mascarons, and here they do the district's talking. Above Royal Indien is one of the rarest: a face with Black features, carved for the wood merchant Joseph Raimbaud. At number 9, and across on allée Turenne at 9, the stone faces carry the same message.
