Here is a few images from the Cement works Ruins on the Mahurangi River, Near Warkworth..This cement works was built in 1884 and closed in 1929, the remains (ruins) of the buildings still stand today...fenced off from the public, with WARNING signs because of the danger of falling rock/concrete pillars etc... but I climbed the fence to gain entry, so I could grab a few shots.

I applied a Chomasolarize filter to each shot to give more of a dramatic look, as the day was rather grey, and skies washed out...
Hope you like them.
