The Dickens Opera House, a venue located in Longmont, Colorado, harbors a rich history and legacy from its beginnings in 1881. William Henry Dickens, who originally built the opera house, obtained the land through his father who was given the land by Ulysses S. Grant. Not only does this land have ties to President Grant, but also to the author Charles Dickens, who was related to William Henry Dickens. While it was renovated a few years ago, the historic roots of this landmark were carefully preserved so that its history could continue to be told and celebrated. Couples now can plan their engagement party, rehearsal dinner, and ceremony is this historic site, weaving their own unique tale within its walls.

Dickens Opera House was an absolute pleasure to work with for the wedding. Their communication style was quick, communicative, and caring - they were always available to answer our questions and address any concerns. The venue itself was even more impressive in person, with lots of natural lighting, wonderful private rooms, a full bar, and an elevator for guests who couldn't or didn't want to use the stairs. They went above and beyond to ensure the day went smoothly, accommodating our specific food requests and making sure we got exactly what was wanted. I highly recommend Dickens Opera House to any couples looking for a beautiful, versatile wedding venue with a wonderful staff.

Awarded Best of Zola
The St Vrain is such a beautiful venue with intentionally decorated spaces. Mark and Annie were wonderful to work with and very communicative. We got married in April and unfortunately were unlucky with the weather, however, we didn’t have to worry much since the St Vrain is primarily indoors, spacious and was easily able to accommodate our 120 guests. Some of their recommended vendors were out of our price range so we had to do a little additional research to find the right vendors for us. Overall, we are extremely glad we chose the St Vrain.
