           Originally a corn grist mill, the 
          mill and woollen factory at Porth y Rhaw was owned and run by Mr Sylvester. 
          To 
          get maximum power from the stream, 3 leats were built further up the 
          valley. On commencing work for the day, the lowest leat would be 
          opened to increase stream flow. During the day as the leats run dry, 
          the next one higher up would be opened. At the end of the working day, 
          the miller closed all 3 leats so that they could refill during the 
          night. On his way home, he probably popped by his garden for some 
          vegetables. The millers terraced garden can be spotted on the east 
          valley side just below the present day pond. Once a year a sailing 
          boat would approach Porth-y-Rhaw to which the miller rowed out to pick 
          up his years supply of die. The mill stood for at least a hundred 
          years before it ceased working in about 1915. 
   
          
            
                  
              The Pumping Station at Nine 
          WellsOn 10th June 1899, the St 
              David's Gas and Water Bill received the royal assent. 
              Within a 
              year, a steam pump was pumping water from the pumping station up 
              to the water tower near Llanruidion (located ½ mile along the road to St Davids on 
              the left) from where the water gravity fed St Davids and the 
              surrounding area. 
              The pumping station 
              was decommissioned during the 1970's after which the Rose Bush 
              reservoir in the Preseli Mountains took over the supply to St 
              Davids and the surrounding area.

          The Quarry 
          Half way down the track to the Mill 
          at Porth-y-Rhaw is a former quarry. Stone would have been transported 
          by pony and trap or horse and cart. 
  
          Iron Age Fort 
          The seaward side of the fort has 
          fallen hundreds of feet into the sea but the landlocked side shows 
          just how strong the defences were. The banks and troughs are clearly 
          visible after 2000 years. There would have been up to eight 
          roundhouses within the safety of the defences.
