Long

The lock keeper house was originally the lock keeper's home. Located along the Somme Canal, it is a place intended for the general public, and offers guided tours, nature outings.

The charming stone and pink brick castle, an 18th century madness, was the work of the best architects of the time, notably Boffrano, who built the Hôtel Soubise in Paris. The Mansart roof gives it all its charm. The 20 hectare park descends from terraced landings to the river. The magnificent listed greenhouses almost have stones in the water.

This specimen of the industrial heritage of the beginning of the XXth century allowed Long to be one of the first villages in France to benefit from the electric current, one of the rare examples in France of small energy production units built in 1914. Visit of 01 / 04 to 31/10

The first church was built in the 12th century, but became too small and therefore enlarged in 1851. It is a neo-Gothic style, with its different capitals, the work of the Duthoit brothers of Amiens. Free visits in July / August, Tuesdays and Saturdays, 4 to 6 p.m. or on request
