A Real Haunted House for "The House of Horror Party".

For the first time, this historic merchant house, known for being haunted, transforms into a multi-level pop-up club with DJs takeovers, themed rooms, and bars for a one-of-a-kind immersive party experience this Halloween!

Brave souls will have the chance to experience Ghost Festivals, House of Horrors DJ Party, a spine-chilling multi-level Halloween party inside a real haunted house.

Steeped in ghostly lore since 1841, the Old Merchant House has long been known for unexplained paranormal activity. Cold chills on the top level, eerie sightings, and mysterious images caught on camera have fueled its haunted reputation. This is not just a Halloween party – it’s an interactive journey into the world of the supernatural.

For the first time, The Rocks’ government has granted special permission to open this heritage-listed venue to the public for an unforgettable Halloween celebration.

Hauntingly immersive multi-room experience

The House of Horrors is no ordinary event – this is a sensory overload where guests become part of the story. From themed rooms and interactive performances to pulse-pounding music, every corner of this haunted house offers a new, eerie encounter.

• THE GHOST ROOM: The centrepiece of the haunted experience. Expect the unexpected as dancers and actors blur the lines between reality and the supernatural.

• THE VAMPIRE DEN: Hidden at the top floor, this dimly lit, gothic bar will lure guests deeper into the darkness. Will you leave unscathed, or will you become part of their eternal night?

• THE ABANDONED HOSPITAL: Enter a decaying medical facility where the line between sanity and madness disappears. The dance floor will pulse with chilling beats while performers dressed as deranged doctors and nurses ensure no one feels entirely safe.

• THE SLAUGHTERHOUSE: Blood-soaked walls, haunting screams, and gruesome surprises await those who dare to enter. Dance among the carnage or flee before you become part of the horror.

DJ collective: WeLove madness takeover

Brace yourself for a night of unearthly thrills as the House of Horrors becomes the ultimate Halloween battleground, with the WeLove collective taking control in a sinister Saturday night takeover. DJs Nick Reverse, André Müller, Corey Kennedy and more will conjure a spellbinding fusion of electro techno, sultry R&B/pop, and bone-rattling tech house, turning the multi-level venue into a haunted labyrinth of beats and chills.

A party with a paranormal edge

What sets this event apart from any other Halloween party is the venue itself. The Old Merchant House is not just a stage for the party—it’s a living, breathing part of the experience. Paranormal investigators and visitors have long reported strange occurrences inside its walls. Cold spots, flickering lights, and the feeling of being watched are just the beginning. Guests have captured ghostly images on camera, and the top floor is known for sudden, unexplained chills. Will you experience something supernatural as you make your way through the haunted halls?
