PRN 60299 This earthwork complex, now partially destroyed by ploughing, occupies a valley site and probably served a multiple purpose as fishponds, wild fowl decoy and drainage. The construction is probably late 17th to early 18th century, during which this type of work was popular. No literary references could be found for this apparently manorial work. {1}{2} It seems unlikely that the ponds were constructed as duck decoys since there appears to be no free access from the ponds into the narrower channels and the large central islands would seem to hinder ducks landing. Probably elaborate fishponds. {1}{3} Local tradition associated these remains with the Templars of Temple Bruer. A historical connection between Rowston and the Templars does exist; in the third quarter of the 12th century the right of presentation to the ecclesiastical benefice of Rowston Church was given to the Templars. Later in the 12th century monies were paid from the church to Temple Bruer. {4}
