The Mail & Custom’s House is rare and historically significant building in Eckerö. It was designed by famous Finnish architects C.L. Engel and C. Bassi and completed in 1828. The purpose of the building was to indicate the power of Russian Empire to seafarers coming from Sweden and it was built intentionally too large for the custom and post office need.
The Mail & Custom's House is well preserved. Today it functions as the post museum and there are temporary exhibitions.
The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
