Fort Lytton National Park - built in the 1800's to defend Brisbane Town, the Fort continued to guard the river for more than a century, has been a quarantine station during the 1918 influenza outbreak and is now administered by Park Rangers and volunteers. They run historic walks and school holiday programmes.
I spent many years living in Brisbane and being a history buff I have SO many favourites.
Customs House on Eagle st is beautiful and still holds lavish balls and functions.
Old Government House has been restored beautifully and now maintained by QUT so is a great place to visit with an awesome outdoor cafe.
Newstead house in Newstead is a classice old homestead with orginal out buildings used by servants. You can even tour the underground rooms such as the kitchen and stores used by the cooks. The gardens are fabulous and the views of the river are stunning.
My favourite would have to be North Pine Country Park on Old Dayboro Road in Petrie. There are so many original buldings lovingly restored. Its free to visit and you can enjoy the weekend markets, dining, activities for kids such as fire engine rides. It was one of my favrouite places to photograph at any time.
Its well worth it Roy. I've been back so many times.I notice you like photography. It is another favourite spot of mine for this. You can drive walk around the garden and grounds at sunset even after the house itself is closed and it has some amazing photographic opportunities. Enjoy :)
City Hall is fun to visit and ride to the top of the clock tower, I also like the Brisbane Arcade for a bit of old world charm - both buildings are apparently haunted, so look out for anything metaphysical around there.
