The Felin Cardau Tide Mill is a complex example of an early tide mill site. The tide was an important source of power for grinding corn from the early modern period until well into the industrial revolution on islands and peninsulas with insufficient drainage for conventional water mills. Unlike other mills which are near the shore and connected to straight dams across narrow inlets, Melin Carnau was built on a small island, with dams in either direction from it across a small bay. The mill platform is visible as low foundations, with the remains of a channel on its west side and the hexagonal collar of an iron wheel.
