Rastoke is known for its water powered mechanical mills. The architectural style of the region combines those of the Dinaric and the Posavina region. The ground parts of the houses are made out of travertine, while the higher parts consist of wood. The roofs are made by shingle or tiles. Due to high concentrations of calcium that regularly sediment at the openings between the cellar stones the ground parts have been covered by a layer of sinter. Thus, water cannot not run into the houses even at high water levels.
