About Us

Twelve Oaks Mansion offers a charmingly timeless backdrop for your celebration. We are nestled perfectly on top of a hill and surrounded by the skies above. Our grounds are picture perfect and offer seclusion for a few private moments and photos together. Sneak away for a minute to our romantic gazebos or to the bench under the pergola. Sit on our front porch and enjoy your first moments as newlyweds.

The Venue is indoor with outdoor space. Inside, you are greeted by a self-playing Baby Grand piano and elegant marble floor that leads to a picturesque winding stairway. The library is the perfect room for your cocktail hour or indoor ceremony. We also have outdoor space available for your ceremony. The Grand Ballroom features glowing chandeliers and seating for up to 250 guests. Windows fill the room and allow an abundance of natural light. We have an open dance floor and an outdoor patio with the most breathtaking views. You get the best of both worlds – an indoor venue with outdoor space. We also have the most amazing sunset views.

If you are looking for an elegant venue, that is customizable and exclusively yours, then send us a message and we we will set up a tour for you.
