The Josephine Mill, a watermill built by Jacob Letterstedt in 1840, has close historical links with the nearby brewery, whose original building this same Letterstedt erected in 1859. The historical interest of the Josephine Mill is, moreover, enhanced by two unique features. It is the only remaining watermill in the Cape Peninsula in which any of the machinery has been preserved; its wheel, made of wrought iron, is virtually intact. In addition, the wheel is the only remaining specimen of its type in South Africa.
