What stands out about Glen Ridge’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1666, 64 Connecticut families led by Robert Treat bought land from the Lenni Lenape Native Americans and named it New Ark to reflect a covenant to worship freely without persecution. The territory included the future municipalities of Bloomfield, Montclair, Belleville and Nutley. When Bloomfield was established in 1812, Glen Ridge was a section "on the hill" composed mostly of farms and woodlands with the exception of a thriving industrial area along Toney's Brook in the glen. For most of the nineteenth century, three water-powered mills produced lumber, calico, pasteboard boxes and brass fittings. A copper mine and a sandstone quarry were located on the north side of the brook.
