Unique Function & Event Venue

The Castlereagh Boutique Hotel is a truly unique venue in Sydney, offering a nostalgic function or event experience with heritage-listed function rooms for up to 150 guests (subject to Covid restrictions)

For brilliant intimate parties right through to extravagant themed events, you can book one of our beautifully restored function rooms with Art Deco architecture. Or you can consider a private area of the Reagh Bar on the ground floor.

If you’re looking to hold a corporate meeting, we have a variety of meeting rooms so you can feel a world away from the office while enjoying our convenient Sydney CBD location.

We’d love to discuss hosting your meetings and events for the year ahead, or we can arrange a site inspection so you can see what we have to offer.
