Eastern suburbs Take a walk on the wild side - on the free Eastwood walk you'll hear tales of past residents, see nineteenth century housing and parts of the old Glenside Hospital (but not Z Ward). May 7 and 14, bookings required.
Save your legs on the free Towers Turrets and Spires bus tour of nineteenth century architecture in Norwood on May 22 (bookings required).
Northern suburbs If you were tempted by the Port Pub Trail, then there are two others at Port Adelaide you may like. The Arresting Tales tour on May 13 explores the 1860 police station, and the Port Vintage tour will showcase a variety of heritage buildings around the Port on May 12, 19 or 26.
Southern suburbs I had never even heard of the Technohistory Museum in the south of Adelaide before, but gadgets interest me a lot. Students have created displays of technology and innovation through history that will be open to the public on May 21 and 25. Definitely one for my calendar. (Free, no bookings needed).
The Mitcham Temperance Hotel with Type A Tram in Foreground
In Mitcham the owner of the old Temperance Hotel has carefully nurtured the near derelict building back to life. Take a free tour of the conservation works, and see how the building looks now. Bookings required.
Another free walking tour of heritage buildings is in Unley on May 15 and 19, starting from the Unley Museum. Hear stories about the chemist, baker and postmaster. Bookings required.
Anyone wanting to keep fit while getting their history fix is in for a real treat in the west. The On Ya Bike events for Brompton and Grange are both free and look like great fun. Just pick up a loan bike and map from the library and off you go about Adelaide. It's best to call first and check bike availability to save waiting.
While you're at the Henley Beach library check out their Corner Shop photo display.
If reading about historic Cummins House tempted you, then take advantage of its Open Days on May 4-5. There's lots to see and it's well worth the gold coin.
Another new museum to me is the Sir Thomas Playford ETSA Museum, open every Tuesday in May. It's all about electricity and power generation, and the million volt spark demonstration has got to be a highlight.
I saved the best one for last for any dipsomaniacs - a free historic hotel bus tour to six pubs in Mile End, Thebarton, and Torrensville. Sadly free drinks are NOT provided, and bookings are required.
Adelaide Hills dwellers have not been forgotten by About Time - an Oakbank Heritage walk brochure which you can pick up from local businesses or download from here. You could even do it as part of a day trip on the Onkaparinga Scenic Drive.
Visit Mike Sheehan's Museum in Mount Barker on Sunday May 12 to see vintage cars, cameras and other fascinating things.
Rail fans will be particularly interested in a talk about the history of the Balhannah to Mount Pleasant spur line on May 9 (bookings required). During the talk you will be able to see rare footage of the last train to use the line in 1963.
Unfortunately space doesn't allow me to cover the events in country towns from the Barossa to Yorke Peninsular, but the range of activities is just as good. Check out the About Time website or pick up a program from your local library for more information.
