Cruze discusses the Endor iron furnace which was built near Sanford in Lee County in 1862. The furnace went into blast in 1863, producing twenty-one tons of pig iron a day for material used in Confederate munitions. No one can say for certain who the builder was or how the furnace got its name. The stones used in the construction weighed between one and two thousand pounds and were joined without using mortar. Today the top left corner of the furnace remains in its original condition, standing thirty-five feet tall and thirty-two feet wide with an eight foot tall open arch on each side. The furnace was placed on the National Registry of Historic Places in 1974.
