This is a first-class Venue for a Celebration of Life. The gardens are absolutely stunning and perfect for an outdoor Memorial. The historic mansion is beautiful inside and out. The staff is amazing! They pay attention to every detail and are a pleasure to work with. I highly recommend the Callahan House to families wishing to have a memorable Celebration of Life in a charming setting.

We had our tiny wedding at the beautiful Callahan house, was lovely. Staff was so ready for everything, so sharp with details, they will keep you calm 100% of the time with a smile. Super affordable, they have so many options and they can also recommend lots of local wedding businesses for services and needs!

The Callahan Garden is open from dawn to dusk to all the residents of Longmont. One of my favorite places in town to visit. Don't forget to look up the history of this local historic family, so fun!!

Beautiful quiet garden. House is very interesting historically. Enjoyed being there.

I recently attended a wedding reception here. It’s a lovely venue! The gardens are just gorgeous and the old house is so beautiful! They had yard games set up for the kids which was fun. The staff seemed to be on top of keeping food & drinks stocked, clearing plates, etc. It would be perfect for a garden party, bridal shower, baby shower, etc, or just a nice place to take a stroll during the day (it’s open to the public dawn-dusk except when a private event is booked)

The gardens are really nice and open daily to the public. Got to see the inside of the house during the open during the September Longmont art walk. I learned that the tile in the bathroom is the original tile so that's cool lol.

Thought this would be a fun photoshoot location, and it is. But it's not anything like people said. Lots of greenery but the lack of flowers was disappointing. That's personal preference though. The garden is beautiful. Great for art deco photograohs

Beautiful venue for upscale parties, memorials,meetings. Limited preferred caterers. Wide spacious wrap around porch that spreads the party out when it is warm enough. Open plan upstairs for lots of different seating options. Gracious house manager with great ideas for overwrought clients.

A beautiful place for a small wedding! The garden is beautiful and the trees provide a nice, intimate feeling in the middle of Longmont. There was some confusion in coordinating with the different vendors, but the day of the ceremony was beautiful and exactly what we were looking for!

The grounds are very beautiful in all seasons, and the architecture is to be marveled at. The inside of the house has a whimsical and very classy movie set quality to it. While well known for weddings, it is well suited for other events as well.

Awesome historic place that my niece had her wedding and reception at

Came for meeting at Callahan and found these beautiful garden flowers😁
