Look Back at Beyoncé and JAY-Z’s Wedding Day as the Couple Celebrates 16 Years of Marriage

In light of the “Crazy in Love” couple’s wedding anniversary on Thursday, PEOPLE is looking back on Beyoncé and JAY-Z’s luxurious (and secret) wedding.

The date was April 4, 2008 — which the couple chose as a nod to their shared love for the number four — and it was held at JAY-Z’s 13,500-sq.-ft. Manhattan penthouse with only 40 guests in attendance.

“It was a very emotional wedding — lots of crying — and really very spiritual,” a source told PEOPLE at the time of the soirée.

At the time, however, the Lemonade singer, 42, and the 54-year-old rapper’s plan to keep the celebration under wraps hit a small bump on the road when they traveled to Scarsdale, New York, to pick up their marriage license in hopes of flying under the radar.
