ARLINGTON, Texas -- Since 1961, Six Flags Over Texas in Arlington has been known for flying six flags over its park.

They represented the U.S., France, Spain, Mexico, the Republic of Texas, and the Confederacy.

Friday morning that all changed when six U.S. flags were seen flying over the park's entrance.

"At Six Flags Over Texas we strive every single day to make people happy and to create a fun, thrilling and safe family friendly experience for our guests," spokeswoman Sharon Parker said. "We always choose to focus on celebrating the things that unite us versus those that divide us. As such, we have changed the flag displays in our park to feature American flags. "

The change came after the park drew criticism from Fox News, TMZ, and others earlier this week, the Star-Telegram reports.

There are 20 theme parks in the U.S., Mexico and Canada that are run by Six Flags Entertainment. Six Flags Fiesta in San Antonio and Six Flags Over Georgia flew the same six flags as Arlington's park, according to the Star-Telegram.

The same change will be made at those two parks.
