Lille (59 Nord, Hauts-de-France) has joined ranks of inland French towns and cities which create a summer beach in town. Often by riversides or in parks, with imported sand, deckchairs and all the paraphernalia of the seaside.
Situated on the Boulevard de Strasbourg on the south side of the City Lille Plage (Lille Beach)is open 6 July – 18 August 2019
and will have a different theme each week – from Beach Rugby, watersports and dancing.
