Since December of 2013, Apple has been building a giant new “spaceship” campus in the company’s hometown of Cupertino, California.

Fans have paid close attention to the structure, almost obsessive. Drones fly by it constantly, and YouTube videos of the building in progress have amassed well over half-a-million views each.

The Apple Park:

The company announced today that the building and surroundings have been named “Apple Park”. The campus will be open to employees starting in April and.

According to Apple, moving the 12,000 employees who will work at the new campus will last more than six months, however the landscaping and construction on some buildings won’t be done until next summer.

The new campus, estimated cost around $5 billion, will replace the Infinite Loop campus Apple has used since 1993, known for its university style. Apple will keep its older buildings.

An homage to Jobs:

Apple will replace the current Town Hall event space with the Steve Jobs Theater, named after its founder and former CEO, the company uses that space for company meetings and product announcements. The theater is set to open later this year.

The new theater is much bigger, it will seat 1,000, compared to roughly 300 for the Town Hall, which will allow Apple to launch more of its products on its campus rather than having to rent event space in downtown San Francisco.

This year, the company is also moving its Worldwide Developers Conference, bringing it back to San Jose after many years at the Moscone Center in San Francisco.

Apple’s new campus was one of the last projects Steve Jobs worked on at Apple before he passed away in 2011. He presented the company’s proposal for the campus during his final public speaking appearance in front of the Cupertino City Council on June 7, 2011.
