It might come as a surprise to some that the Boston Public Library is a popular wedding destination. Unless, of course, you’ve seen the interior, which is renowned for its grand architecture. The library's Abbey Room, named after mural artist Edwin Austin Abbey, is adorned with a spectacular depiction of Sir Galahad’s quest for the Holy Grail.

Now couples can make use of this regal space for free—providing they don’t mind rushing their vows a bit.

To celebrate the 125th anniversary of the McKim Building, the BPL is offering four couples the opportunity to get married for free inside the Abbey Room at the Central Library in Copley Square. The giveaway—which is free to enter—includes a catered breakfast, music, photography, overnight accommodations, and a justice of the peace. The four winning couples will visit the Central Library on Sunday, February 2, 2020 for the ceremony.

Is there some fine print? Naturally. Each couple will be allowed just 10 guests, and the entire affair is scheduled for one hour before the next couple moves in.

If you don't mind the rush, the savings can be significant. Wedding advice website Woman Getting Married reports that reserving the BPL for a ceremony can range from $8450 to over $15,000, with another $400 per guest for amenities like food.

You can enter the giveaway at the Boston Public Library’s website. The winners will be randomly selected. The contest is open through November 15.
