Coplay is where Portland cement was invented by Saylor and these kilns were the last and most effective kilns in use at the time rotary kilns were invented. Originally 40 feet taller than they are now and housed in a 4 story building, they were built in 1892 and operated about 10 years. At one point the region produced about 70% of all the cement used in the USA. Interesting history. Very fine ride too thru that history. Oh, I was on my dropped Trek 850 again but youse allz seen that ole wreck.
