What to know about The Vault, package options, and entertainment logistics before you book your wedding at this historic downtown venue.
Treasury on the Plaza sits at 24 Cathedral Place in the heart of downtown St. Augustine, inside a building that opened as a bank in the 1920s. An award-winning renovation turned the space into one of the city's most distinctive wedding venues, keeping historic details like the original bank vault while adding modern event infrastructure.
The venue is part of the Treasury Venue Collection, and books exclusive-use weddings only — when you're booked, the entire building is yours for the day, not shared with another event.
Treasury on the Plaza hosts weddings from 40 to 175 guests, and offers three main package tiers rather than an a la carte room rental:
| Package | Best For |
|---|---|
| Custom Wedding Package | 40–175 guests, choose your own vendors |
| Eat, Drink & Be Married | 100–175 guests, venue/food/coordination/bar included |
| All-Inclusive Package | 100–175 guests, most vendors bundled in |
The venue notes it works best for weddings in the 75–150 guest range — large enough to feel celebratory, small enough that the historic space doesn't feel empty.
Treasury on the Plaza is a fixed historic building rather than a flexible ballroom, so your DJ's setup has to work within the existing architecture — including The Vault area, which is a popular but acoustically distinct space compared to the main reception floor.
What we'd confirm before your wedding day: which package and spaces you've booked, whether The Vault is used for cocktail hour or part of the reception, load-in access downtown, and power availability for the room configuration you choose.
As a St. Augustine wedding DJ company, we plan sound coverage around the venue's actual layout rather than a generic ballroom setup.
From as few as 40 guests up to 175, with the venue working best for gatherings of roughly 75 to 150 guests.
Yes. When you book your wedding ceremony and reception here, you receive exclusive use of the historic building for the day.
The Vault is the original bank vault from the building's 1920s history, now used as a striking bar and photo backdrop for receptions.
Because the venue is a converted historic bank building with a fixed indoor footprint, your DJ needs to plan sound and setup around the room's existing architecture and load-in access.
