(NPR) - In America, vineyards are usually tucked in out-of-the-way rural areas, among country lanes. But in France, where great wine is a way of life, vineyards are everywhere — even in the middle of the country's biggest city. High on the hills of the neighborhood of Montmartre in Paris is Clos Montmartre, the city's last working vineyard. Every year for a week in October, residents from the Paris neighborhood pour into the streets to celebrate their grape harvest, a festival known as the Fete des Vendanges. There is a costume parade, street performances, concerts and giant picnics — all in honor of a small patch of land on a slope surrounded by houses with Mansard roofs.
