Camelot
From Memory Alpha, the free Star Trek reference
Camelot was the name of a legendary location from where King Arthur ruled Great Britain.
Jadzia Dax and Kira Nerys often visited a holosuite program based on Camelot. (DS9: "The Way of the Warrior", "The Muse")
Camelot was to be the setting for the TNG: "Qpid", but this was changed to Sherwood Forest to build on the popularity of Robin Hood: Prince of Thieves. (Star Trek: The Next Generation Companion)
