The Ferrari World theme park in Abu Dhabi will not open today as planned.

ArabianBusiness.com is reporting that the theme park's opening has been postponed following the death of Sheikh Saqr Al Qasimi, the ruler of Ras Al Khaimah.

The park was expecting more than 10,000 visitors on its opening day today.

Seven days of official mourning has been declared in the United Arab Emirates. Ferrari World officials said that as a show of respect, the park's opening will be postponed until Nov. 4.

Ferrari World is being billed as the world's largest indoor theme park. The attraction on Abu Dhabi's Yas Island has more than 925,000 square feet under a roof shaped like the double-curve side profile of a Ferrari GT.

It will feature the world's fastest ride - the Formula Rossa roller coaster, which is expected to reach top speeds of more than 150 miles per hour.
