. . . the lane wends its way up the valley, with Glasffrwd . . . babbling over its rocky course, on the right. Here you are at once in the heart of the country ‘Alone with the Alone’ the sky, water, mountains, trees, rocks and birds. The monks new well the value of this spot, here were nay, still are their wells of healing waters, iron, sulphur, chalybeate used with benefit by the natives to-day. What more truly romantic spot can be imagined or desired than that round ‘Ffynnon dyffryn tawel ()' the ‘Well of the silent grove’? Here its cool waters still bubble forth, much as they did when pilgrims to the Abbey slacked their thirst at its welcome brink
Abaty Ystrad Fflur was sited at the junction of two rivers, the Teifi  and its tributary the Glasffrwd. The waters of the Glasffrwd were used, in part, for drainage within the abbey and, also, to service the water mill. In 1903 George Eyre Evans (www.hanesybont.org.uk/welshtravellers/georgeeyre.htm) described a walk along the lane leading from Ystrad Fflur up the Glasffrwd valley
 Ffynnon dyffryn tawel is about 10 to 15 yards above where this picture was taken
