A park in Belfast, Northern Ireland, that's been divided by a "peace wall" for 17 years has had a gate installed.
The three-metre high fence was put up in Alexandra Park to stop fighting between Catholics and Protestants.
It means that children from the two sides no longer have to play in separate playgrounds.
The new gate will be open between 9am to 3pm on weekdays for a three-month trial period.
In the past, there's been lots of violent clashes between Catholics and Protestants, who have disagreed over who should rule Northern Ireland. But things have got much better recently.
There are 49 "peace walls" in Belfast at the moment. If the trial goes well, it could pave the way for other walls to come down.
