GUID (UUID V4):

"Granite" quarries, opened in 1824 for the construction of the armory at Springfield, Massachusetts. Biotite-quartz monzonite gneiss with pegmatite bands up to three inches thick.

A railroad was constructed in 1875 to connect the quarry to the New London & Northern RR mainline (now the New England Central RR). By 1997, the entire quarry had been back filled and is now a simple grassy field.

According to L. Everts (1879): The stone is a beautiful stratified gneiss. It is chiefly of a grayish tinge though other shades appear also, free from oxide of iron and other mineral impurities, and is easily wrought by the process of wedging, no blasting being necessary. The largest stone over quarried there was 354 feet long, 11 feet wide, and 4 feet thick, taking 1104 wedges to split it. Many public buildings have been erected of this stone, including the court-house at Springfield, and the Boston and Albany Railroad offices. The church of St. Francis Xavier (R. C.) in New York City is now being erected of stone from this quarry.
