Skydeck Chicago has announced its annual "Love on The Ledge" social media contest.

The event at the Willis Tower observation deck gives adventurous couples of all backgrounds the chance to tie the knot or renew their vows in a private, romantic ceremony 1,353 feet in the sky.

To enter the contest, couples are invited to submit a photo or video entry on Skydeck's Facebook page, Website Link Here , through Friday, Jan. 28, sharing their love stories and why they wish to experience Love on The Ledge. On Tuesday, Feb. 1, up to four couples will be selected as winners of a private wedding ceremony or vow renewal on the nation's highest observation deck to take place on Feb. 13, the Sunday of Valentine's Day weekend.

Each winning couple will enjoy a private 15-minute vow renewal or wedding ceremony with the Chicago skyline as the backdrop, complemented by romantic floral and décor, and can be accompanied by up to eight guests. Further, couples will receive a stay the night before at Canopy by Hilton Chicago Central Loop (located directly across the street from Willis Tower); professional photo shoots taken during and after the ceremony; and deluxe offerings on site, including breakfast and a champagne toast.
