The festival organised by Birmingham Museums Trust aims to let residents and visitors find new parts of Birmingham they have never seen before as well as rediscover well-known sites, but see them from a new perspective.
At the centre of this year's Heritage Week is the hugely important story of The Lost Children. This exhibition at Birmingham & Midland Institute, in Margaret Street, showcases the emotional and fascinating life stories of just a few of the 6,000 destitute children sent from Emigration Homes in Highgate, Birmingham, to live with farmers in Canada between 1873 and 1948.
It's a little known story about what used to happen to children aged from as young as two to eleven and is sure to be emotive. The exhibition runs from 14 to 22 September and is open between 10am and 4pm.

Elsewhere, visitors will also be able to discover the Secret Gardens of Handsworth from 1pm to 3pm on 20 September. A specially-extended tour will take people through magical walled gardens behind nine striking Georgian houses, which are usually closed to the public. The tour starts at Soho House Museum and costs £5 per person.
Bringing to life the role of those 'downstairs', there is a special guided tour on 12 September at 1pm at the beautiful Jacobean mansion of Aston Hall, which focuses on the lives of servants in the 17th century.
There will also be a chance to look closely at the Victorian architecture and artwork in the beautiful Waterhall Gallery, which is part of Birmingham Museum & Art Gallery.
In terms of the city's art venues, Ikon Gallery will also have an exhibition on display by Stuart Whipps about the former car factory at Longbridge from 11 to 15 September. The show reflects on the closure of the Longbridge motor works in Birmingham, which is part of his long-term art project The Kipper and The Corpse.
The factory was the last British-owned volume car manufacturer that was responsible for making Rover cars for many decades. Through making the project, Whipps seeks to understand its inevitable closure that devastated the south part of the city.
Meanwhile, the historic suburb of Bournville, famous as the home of Cadbury's chocolate, will have an open day on Saturday 14 September when many of the area's historic buildings will be open to the public for free.
And there will be rare access to all the First World War Bilberry Hill Gun Proof Range sites in Lickey Hills Country Park where guides will explain the history behind these remnants of World War One on 21 and 22 September from 11am to 4pm.
Irene De Boo, Coordinator for Birmingham Heritage Week 2019, said: "We're back with a brilliant array of events for Birmingham Heritage Week 2019 and the listings are even easier to navigate on our website, so it's the perfect time for visitors to start planning and filling up their diaries with exciting events."
