a town of France, department of Seine-Inferieure, arrondissement of Dieppe, and 17 miles N.N.E. of the town of that name. It is situated on the small river Bresle, about two miles from its mouth, in the English Channel, and contains about 4000 inhabitants. Eu was a place of some importance in the middle ages, but it was burned by Louis XI. in 1475 to prevent its falling into the hands of the English, and has never attained its former condition. It is chiefly remarkable for its château, built by the Duke of Guise in 1578 on the site of a castle destroyed with the rest of the town in 1475. This château was greatly enlarged and richly decorated by Louis-Philippe, to whom it came by succession, and here he received the Queen of England in 1843. It is surrounded by an extensive park and gardens. The parish church is a fine Gothic edifice, under which is a crypt containing numerous monuments of the Artois family.
