Photo DPM 9.  (left) shows the relative positions of the Perišić Ponor-mill (lower right) and the Drapić Ponor-mill
(top centre) on either side of the Trebišnjica River. 
The standing figure indicates the previous river level a few hours before the photogragh was taken.

Left-side Column:
Photos DPM 10. & 11...(top-left) show details of the exterior circumference of the outer cylindrical stone wall - the coffer dam.
The protruding stones are immediately above the water gate (penstock) and indicate where the screw mechanism would have been located
for raising and lowering the water gate.
(Photos :  B. Lewarne, 13 Aug 2000.)

Photos DPM 12. & 13.  (middle-left)  show the position and condition of the spiral stone staircase on the inside of and contiguous with the outer cylindrical stone wall.  Note the profusion of plant growth.
(Photos :  B. Lewarne, 13 Aug 2000)

Photos DPM 14. & 15...(bottom-left) shows in greater detail the damage caused to the masonry of the spiral stone staircase by excessive root development of the trees and bushes growing inside the ponor-mill.

Photo DPM 28...(left) illustrates the Perišić Ponor-mill in context and indicates the condition of one of its ancilliary buildings.
The "shell" of one of the ancilliary buildings is plainly seen to the rear of the ponor-mill and in front of the inhabited building in the centre-right of the view.
Interestingly, the vegetable gardens associated with the ancilliary building were still tended when this photo was taken.
There are other apparently associated out-buildings which are inhabited.

Left-side Column:
Photo DPM 17.  (left-top) illustrates the Perišić Ponor-mill set low into the bedrock limestone, with its exterior integral stone steps.
(Photos :  B. Lewarne, 28 Aug 2001)

Photos DPM 18. & 19.   indicate the stranglehold of the foliage upon the inner spiral stone staircase.
(Photos :  B. Lewarne, 13 Aug 2000)

Photos DPM 20. & 21.  indicate the inner Mill House at the bottom of the spiral stone staircase.
Malcolm Hardman is standing at the doorway looking in at the litter-strewn floor of the building.
(Photos :  B. Lewarne, 13 Aug 2000)

Photos DPM 22., 23. & 24...give details of the Millstones above the turbine chamber.
In the centre of the circular mill-stone can be seen the orifice through which would have
protruded the drive-shaft from the turbine below.
(Photos :  B. Lewarne, 13 Aug 2000)

Photos DPM 25., 26. & 27.  show views looking down into the Turbine Chamber through the access opening.
The middle view shows the original cave wall at the entrance to the ponor proper and the right view shows the vertical turbine drive shaft and
turbine structure.
(Photo :  B. Lewarne, 13 Aug 2000)


Photos DPM 29. & 30. (above) indicate details of one of the the breaches in the concrete (shotcrete) lining of the riverbed exactly in the location where the water inlet structures to the Perišić Ponor-mill should be located.
