Hackney was a parish in the historic county of Middlesex. The parish church of St John-at-Hackney was built in 1792, replacing the nearby former 16th-century parish church dedicated to St Augustine (pulled down in 1798). The original tower of that church was retained to hold the bells until the new church could be strengthened; the bells were finally removed to the new St John's in 1854.
