Mount Stromlo Observatory Canberra
Devastated by a severe bushfire in 2003, the Mount Stromlo Observatory no longer undertakes active astronomical observations. Instead, it has become the headquarters of the ANU (Australian National University) Research School of Astronomy and Astrophysics. Despite the destruction caused by the bushfire, the ruins of the observatory domes are worth visiting.
History
The first telescope installed at Mount Stromlo was the 9-inch Oddie Telescope (so-called because it was gifted to the Commonwealth by James Oddie, a wealthy Victorian businessman and philanthropist.). Following the Oddie’s findings that this was a suitable location for an observatory, the Commonwealth Solar Observatory was established in 1924. Up until the Second World War, its primary focus was solar and atmospheric physics.
During the Second World War, the observatories’ workshops manufactured gun sights and other optical equipment.
Post war, the observatory commenced the study of stellar and galactic astronomy. Renamed The Commonwealth Observatory it continued these studies until 2003.
2003 Bushfire
On 18 January 2003, the devastating Canberra firestorm hit Mount Stromlo (which was surrounded by a plantation pine forest), destroying five telescopes, workshops, seven homes, and the heritage-listed administration building. The only telescope to escape the fires was the 1886 15-centimetre Farnham telescope.
The fire was so intense it melted the optical glass of some telescopes. It was decided that the observation domes and telescopes would not be rebuilt and all observations are now undertaken at the Siding Springs Observatory. However, the workshops were replaced and now produce state of the art astronomical instrumentation.
Getting There
Driving to Mount Stromlo takes around 20 minutes from Canberra, with a carpark located next to one of the burnt-out domes. The last section of road is two-lane but narrow and winding. Cyclists use this section so be careful if you need to pass them on either the uphill or downhill section.
What to See
Unfortunately, both the Visitor Centre and Cafe were closed during our visit (January 2024). However a self-guided Heritage Trail loops through the area, enabling you to see experience the area. Walking the trail takes you past all of the domes, several of which are accessible. Information boards placed throughout the observatories’ ground detail the history of the area and the devastation of the 2003 fires.
The damaged caused to the area is very sad, considering the amount of scientific work that was undertaken here. Preserving the ruins however was a great idea, as you still get a feel for what was achieved as well as the loss.
Small outreach telescopes are available for hire with a private star gazing session. Public star gazing is available from April to September each year.

Interesting Destinations Journey! I laughed at that Storm Trooper!
The storm trooper was sort of relevant to the observatory. Still loved it.
The ruins are amazing contrast to the modern white technology! The stormtrooper is a nice touch!!
