Hooghuis.  The "Hooghuis" (High House) is the oldest building of the village and was commissioned by the Polder administration and built in 1613-1614. Because the mansion was once property of the Brandt family, it is also linked to the Rubens family. It is a protected monument containing several original features. When the Saeftinghedocks will be constructed, the house is planned to be rebuilt in another location.
Address: Hooghuisstraat 8, Doel

Mill.  The windmill of Doel was built in 1613-1614 during the 12-years truce, at the same time that the village was laid out according a geometrical plan. Back then, it was already a stone mill, which makes it one of the oldest surviving stone mills in the country. It was restored in 1958 and served later on as restaurant. When the Saeftinghedocks will be constructed, the mill is planned to be rebuilt in another location.
Address: Scheldemolenstraat 6, Doel
