XXXTentacion's been laid to rest and won't soon be forgotten by his loving family and fans, but just to be sure ... he got a huge monument in his honor.
X's mother, Cleopatra Bernard, just shared a photo of the rapper's mausoleum with the caption ... "My guardian angel." As you can see, it's been surrounded by flowers, too.
His private funeral was held Thursday in Florida, and was reportedly attended by fellow rappers Lil Uzi Vert and Lil Yachty, and singer Erykah Badu.
As we reported, though X was only 20 when he was shot and killed ... he left behind a will, with everything going to his mom and brothers.
