LOS ANGELES — Welcome to a Britney Spears fantasy land: the Britney of the past, the Britney we want her to be.

Britney Spears the Zone, a 30,000-square-foot fan-generated experiential pop-up dedicated to the career of the Princess of Pop, has been erected at a time when there’s no sign of her return to Vegas — or the stage anywhere — and she is still under personal and financial conservatorship.

It includes 10 rooms that each recreate an iconic music video set, album concept or live performance, beginning with a “…Baby One More Time”-inspired high school classroom.

There, a video featuring Ms. Spears’s longtime friend and erstwhile assistant, Felicia Culotta, plays from a 150-inch customized LED screen. A special film was applied to the outside to make it look like a chalkboard.
