Portes of Call represents Bob Downton's second photographic exhibition at Hamilton HIStory + HERitage. His first was called inSPIRED - Hamilton Church Spires. This exhibition features Bob's photographs of "working" doors all over Hamilton. Each door was one that workers went through each day to earn a living, some at large factories, others at small workshops. Most have been closed for many years. But all have a history. Bob's photographs capture the industrial beauty of these wonderful entrances around Hamilton.
