The Hur'q Central Museum was a subterranean building on a Hur'q planet in the Gamma Quadrant that housed treasures taken by the Hur'q from other worlds. Some artifacts even came from Alpha Quadrant worlds. It contained security technology such as holographic fake walls, lifesign access sensors and force fields.
In 2372, Worf, Jadzia Dax, and Kor entered the Hur'q Central Museum looking for the Sword of Kahless. While the museum had been looted by others, the three discovered a holographic projection that hid the chamber containing Kahless' bat'leth from view. (DS9: "The Sword of Kahless")
