Around the Long lock

Highlight • Structure

The private property of Long, open to visitors, is located in the heart of the Somme between Abbeville and Amiens. Classified as a historic monument, the building, dating from the first half of the 18th century, features architecture in the Louis XV style, made entirely of pink bricks and white stones.
The Château du Long is shaped like a rectangular central body with a mansard roof, inside which are very beautiful sculptures and paintings by Huet. The site is surrounded by a magnificent park of about twenty hectares, with French-style shrubs, greenhouses and a listed washhouse, an 18th-century dovecote, an orangery and a cooler, a six-hectare pond, outbuildings or a four-hectare wood. Very beautiful statues also mark the alleys that invite you to stroll. (France-Voyage)
