St Augustine's Tower stands in St John's Church Gardens, in
Hackney Central, in the
London Borough of Hackney, just off the southern end of the Narrow Way (formerly Church Street). It is all that remains of the early 16th century
parish church of Hackney of
St Augustine, which replaced the 13th century
medieval church founded by the
Knights of St John. The Tower comprises four stages beneath a restored parapet with diagonal buttressing. A fine working 16th century turret clock has remained on the third floor of the Tower since at least 1608. The Tower and contents are
Grade I listed.
