Sydney Observatory and Observatory Park
Sydney Observatory is a historic site, a museum and a park all in one
The Sydney Observatory is our only attraction to be listed under three different categories. In addition to being a historical site it's also a museum and the surrounding gardens form a lovely park with superb views.
Day or night it is free to enjoy a stroll around Observatory Hill Park where you will be treated to panoramic vistas of Sydney Harbour including the iconic Sydney Harbour Bridge. Consider visiting during the early morning or at night to avoid the busiest times. You can also see the exterior of the heritage-listed Observatory through the gate.
Sydney Observatory Tour
If you would like to explore inside of the Observatory compound and enter the Observatory itself you can book a Sydney Observatory Tour. The one hour tour, available Wednesday to Saturday leads guests through the Observatory's grounds, revealing the stories behind Fort Phillip, the bombproof shelter, the flagstaff, and the numerous buildings on site. Visitors are invited to step inside the Observatory building to explore objects from the Powerhouse collection and investigate the site's role in surveying, timekeeping, and astronomy.
Ascending the Observatory's narrow staircases, guests will be able to venture into the astronomy domes, where they can witness historic and modern telescopes in action. From this stunning vantage point, visitors can take in the breathtaking view of Sydney Harbour and, when conditions are suitable, observe terrestrial objects through a telescope.
It is important to note that the tour includes approximately 125 stairs, some of which have no wheelchair access due to the steep and narrow staircases of the heritage-listed site.
Sydney Observatory Family Tour
A Family Tour that is more suited to families with younger children between age 6 and 12 operates on Friday and Saturday evening.
In the event of rain, tours will be cancelled and payments refunded. Cancellation notices will be sent to participants by email four hours prior to the start of the tour.
Sydney Observatory Late
Sydney Observatory Late is a free program occuring once each month and offers an evening of stargazing, lectures from distinguished astronomers, and live music and performances.
The program is tailored to events taking place in the night sky and includes informative astronomy talks, as well as telescopes for observing the stars. Guests can enjoy live music, and food and drinks are available for purchase.
Sydney Observatory History
Construction of the Observatory took place from 1857 to 1859. It is strategically located on the highest ground overlooking Sydney Harbour. The first purpose of the Observatory was to keep accurate track of the time based on the positions of the stars. A time ball located on a pole on top of a tower is dropped each day at exactly 1pm as a time signal to ships in the harbour.
Beginning in 1887 the Observatory participated in a world-wide project to map and photograph the entire sky. It was nearly 80 years later when the Sydney Observatory had finally completed the large portion of sky that was allocated to them.
The observatory was also responsible for keeping records of meteorological observations and, for over a century, it served as a signal station using various flags to relay information about arriving ships or to communicate weather conditions to the port authorities and to other points around the harbour.
Recent archaeological excavations have clearly revealed the foundation walls of Fort Philips which was built between 1804 and 1806. The Fort even had a bomb shelter, but its primary purpose soon changed to that of the shipping signal station described above.
Without a doubt, a visit to the Sydney Observatory and Observatory Park should be high on your list of things to see and do in Sydney.
Nearby attractions include: Garrison Church, The Rocks and Sydney Harbour Bridge.

Didnt know such a beautiful place existed before going to make lanterns for moon festival today. The staff were all very nice and lovely, especially Jack who was super cool and took the time and effort to show us the moon and sun through the telescope. Thankyou for providing a great experience there.

This is a real treat for a history buff or an astronomy/space buff! We took the Guided Family Tour and Jack, our guide, was an amazing teacher. The kids in the group had the chance to open and rotate the huge metal domes of the observatory.
We saw how a modern telescope operates using the latest control systems, in contrast with a 150-year-old gigantic telescope. On a sunny day at noon, we saw the dark spots on the Sun, and the stars Alpha Centauri AB and Beta Centauri. We also got to see a clock tower 2.5 km away, up close (and upside down)! One amazing kid in our group even got the privilege to look at the Sun through the optical filter of the telescope!
The history part of the tour taught us a little bit about signalling using flags and we hoisted a pirate flag and a temperature flag on top of the flagstaff. Jack encouraged questions from all of us and he even replied "I don't know" to a couple of intelligent questions from the kids! Kids and adults will truly learn many interesting things from a visit. The tour of the observatory is highly recommended.

Sydney Observatory is one of those places that quietly steals the show. The walk up the hill from The Rocks shifts you out of the city rush, and suddenly you are in a pocket of lawn, jacarandas and sandstone with the harbour spread out like a painting. The building itself feels beautifully looked after, all brass fittings and creaking floorboards, and the little domes hint at what is upstairs. Arrive late afternoon if you can, watch the light slide across the bridge, then step inside as the rooms glow warm and the city begins to sparkle below.
By day it works as a small museum you can actually take in. Displays cover timekeeping and navigation, there are instruments you can see up close, and the stories are told simply enough that kids lean in without wandering off. Solar viewing sessions, when they run, are a neat way to put the sun into focus. At night the tone shifts from history to discovery. Guides are generous with their knowledge, pointing out the Southern Cross, the Magellanic Clouds and whatever planets are playing nicely that week. Looking at Saturn’s rings through a telescope never gets old, and the planetarium show ties it all together so you know what you are seeing when you step back outside.
A couple of things made my visit better. Booking ahead is smart because sessions are intimate and they do fill. Give yourself extra minutes for the climb, the paths are short but steep in spots, and the hill can be breezy after dark so bring a layer. Cameras are welcome on the grounds, just keep screens dim during stargazing so everyone’s night vision survives. Families are well catered for, the staff are patient with questions, and the gift shop has the kind of science toys that actually get used. It is a calm, thoughtful way to spend a few hours and you leave seeing the sky with fresh curiosity.

This evening, we completed a tour at the observatory lead by Bajwa. He was awesome and super informative. Tour covered some of the history of the location and of astronomy in general. We were then shown the moon and Saturn via the modern telescope there, followed by a look through a super old telescope.
10 of 10 would do again! Thank you Bajwa!!!

Had an interesting historical night tour with Steph last week. She was really cheerful.
* Do avoid the tour during raining weather * because they can’t open the dome in rain and you can’t use the telescope to see stars.
