Chip and Joanna Gaines renovate a castle in the trailer for their new show

• Chip and Joanna Gaines have been renovating a castle in Waco, Texas, since 2019.
• They documented the project for their upcoming show, "Fixer Upper: The Castle."

Chip and Joanna Gaines gave their fans a first glimpse of their latest renovation project: a castle.

The "Fixer Upper" couple bought the castle in their hometown of Waco, Texas, in 2019, fulfilling a decades-long dream of Chip's, as Joanna wrote in a blog post.

Chip and Joanna have also been documenting the renovation for "Fixer Upper: The Castle," which premieres on Magnolia Network, HBO Max, and Discovery+ on October 14.

The official trailer for the series dropped Friday, providing a sneak peek of the massive renovation project.

"This castle is one of the most impressive properties in the entire Waco, Central Texas area, and I've wanted it for two decades now," Chip said in the trailer.

As they explain in the trailer, the castle project is unique for the Gaineses because it is a restoration rather than a fixer-upper.

They went into the project with the intention of putting it back into its original state, which is quite an undertaking; the property was originally completed in 1913 and fell into disrepair in 1991, according to Magnolia.

"Getting the same exact stone from 100 years ago has been a challenge," Joanna says in one moment from the trailer.

In addition to watching the renovation unfold on Chip and Joanna's upcoming series, "Fixer Upper" fans can also tour the castle in small group tours through October.

The majority of the tour will focus on Joanna's approach to designing the house, though visitors will also learn about its history.

"The doors are open once again, and we can't wait to host you here at the Castle so you can experience this stunning historical home in all its glory," the Gaineses added.

The tours are currently running and will continue through October 26. Tickets cost $50, though children 7 years old and younger can attend for free.
