The Vault Bar can be found at The Treasury on the Plaza - a premiere event venue in St. Augustine, Florida. The venue boasts 6,000 square feet of historic space, capable of accommodating up to 450 guests for a reception, wedding, or special event. For seated dining, the venue can hold up to 300 people, while standing cocktail parties and gatherings can comfortable hold up to 450 people. The venue consists of the Grande Ballroom, Vault Bar, Banker's Lounge, Exchange Gallery, Plaza Lounge, and on-site parking. The lounges may accommodate brides and grooms for wedding preparation. 

The building that holds this venue was originally built in 1927. It opened the same year as the Bridge of Lions and served as a landmark bank on Cathedral Place before recently being converted to an event venue. The towering atrium at Treasury on the Plaza has Roman-style columns, and the old bank vault in the back has been converted into a bar. The building is listed on the National Register of Historic Places.

There are four separate floorplans to choose from for every occasion, whether it's a coporate party, family reunion, or wedding reception.

Treasury on the Plaza is located in the tall building on Cathedral Place, across from the Plaza de la Constitución.
