104 (Centquatre)

It's more than a century since Montmartre was the centre of artistic activity in Paris. But now the north of Paris is again where the action is - albeit a couple of kilometres east of place du Tertre, in a previously neglected area of bleak railway goods yards and dilapidated social housing.

104, described as a 'space for artistic creation', occupies a vast 19th-century building on the rue d'Aubervilliers that used to house Paris's municipal undertakers. The site was saved from developers by Roger Madec, the mayor of the 19th, who's made its renovation the centrepiece of a massive project of cultural and urban renewal.

There aren't any constraints on the kind of work the resident artists do - 104 is open to 'all the arts' - but they're expected to show finished pieces in one of four annual 'festivals'. And they're also required to get involved in projects with the public, the fruits of which are shown in a space next door.
