A significant estate gracing the town of Longmont, CO, Historic Callahan House & Garden grants couples a wedding venue imbued with both elegance and charm. Built in 1892, the home is furnished with authentic period furniture and decor, from the 1893 Steinway piano to the parquet inlay floors, adding a feeling of elegance. Finding shade amongst the trees and fountain gurgling in the garden, this Victorian home provides intimacy and refinement for quiet, sophisticated weddings.
The Historic Callahan House & Garden is an ideal setting for small-scale nuptials; the house can host 32 guests for Sweet & Simple off-season weddings, and in the summer, the garden can host up to 125 people. With funding from the city of Longmont, the buildings and grounds have been restored and maintained to contemporary standards. The automobile house is distinctive among the estate, which provides a touch of antique interest. The ornate details throughout this location are sure to allure and enchant, bringing guests and the wedding party into a storied romance. The house itself is Queen Anne style Victorian, embellished with delicate warm touches. Bowing toward refinement and European aesthetics, it is decorated with a French interior and nestled in an Italianate Garden. With a black walnut and cherry stairway and stained glass and beveled windows, this locale boasts a vintage tenderness for couples seeking a timeless charm. The details of this mansion provide a setting swirling in nostalgia, a perfect setting for celebrating the love of a couple and their own romantic history.
Couples can rent the house, garden, and auto house, or combinations of the three, giving flexibility for the special day. Callahan House is proud to partner with our outstanding preferred caterers. Tables, chairs, and dance floor are included in all wedding packages. Dinnerware and linens are all available for rent through your caterer. Weddings at the Historic Callahan House & Garden will surely transport couples and guests to a bygone era imbued with upscale beauty.

were efficient and effective at setting up both. Kathy was knowledgeable and friendly, and it was clear her main goal was to make the night what we wanted. In our case, we wanted something low key and fun, and she supported our choices and offered informed advice to make it work. I would definitely recommend Callahan House to anyone looking for a smaller, friendly, beautiful venue!

Our guests were IN AWE of how beautiful the gardens were and loved exploring the beauty of the historical house.

everything we might have forgotten, booked all the set-up for us, including a tent I added at the last minute, handled the liquor license and had the site looking wonderful when we arrived. She also suggested some caterers and we chose Green Points, The food was absolutely delicious and we got many compliments from guests. The two staffs worked together flawlessly. I can't say enough about both of them and I wouldn't hesitate to use them again.

ooking at other venues as it seemed the proprietors were not as open to LGBT weddings, fortunatly this was not the case here. The staff helped us to flesh out aspects of our wedding that we had not planned and were more than willing to suggest local vendors to fill any gaps. We had to keep everything small due to COVID but Kathy and her team worked diligently to make the day as special for us we could have hoped for.

beauty. The history of the house is maintained with pride, honor and an attention to detail that maintains its charm. We had to reschedule the wedding twice because of the pandemic and Kathy was very kind and accommodating whenever we communicated. We also did our engagement pictures at the venue and a small 2020 ceremony; every time we have been to the Callahan Kathy made us feel so comfortable and went above and beyond to make it our special day.

My friends and family absolutely loved the Callahan house for our June wedding! The flowers were at their prime (no decorating!) and the lawn gave some of the kids room to be kids....
History buffs loved the house's story and admired its historic interior. Our wedding was in the middle of losing my Father to cancer, and Kathy, the house manager, carried us through this time with extra support before the reception and during the day. It would not have gone so smoothly without her expertise and thoughtfulness. I can't say enough about how great this place is...

The gardens are beautiful and the house was a perfect backdrop for all of our photos. Our wedding day was absolutely perfect here, with one exception: the house manager Kathy was a...
nightmare. She was great in the months leading up to the wedding, although she did try to control a lot such as the colors we chose and how we wanted our seating chart. But on the actual day of the wedding she was a nightmare.
Not only did several of our guests and my mother complain about how rude she was to them, but she even snapped at several of my family members when I asked them to help me begin packing things up a the end of the night, and my photographers had horrible experiences with her as well. One photographer called her ahead of time to make sure their timelines for the day matched up and Kathy actually hung up on her! And when the photographers arrived about 15 minutes early to scope out photo locations Kathy refused to allow them inside, even though it was only 15 minutes. She did the same thing to us as well, we arrived about 10 minutes before expected and found the house locked so we rang the bell. Kathy left us standing there for five minutes and though she did then allow us inside, she docked time from the event (you get a set amount of time for the venue) which meant my guests had to leave earlier than planned at the end of the night.
Rather than just watching from the sidelines as I've seen done at weddings at other locations, Kathy hovered around my guests the entire wedding. She even ended up in every single photo of me walking down the aisle because she was standing directly at the entrance of the aisle. She also ended up in every photo of my husband and I signing our marriage license. My photographers tried to work around this, but it was inevitably unavoidable.
As the wedding wound down she took it upon herself to take all of our things from the house and DUMP THEM ON THE PORCH. Since I knew we only had about a half hour left I was walking to the front of the house to begin gathering our things and saw everything just sitting on the porch. Kathy and another woman were just shoving it all out there. My makeup, jewelry box, guest book, all of our belongings were essentially just thrown out of the house which myself and the remaining guests found to be horribly rude.
The venue itself is absolutely stunning and we did have a great time, but if you are not the kind of bride that is willing to have a strong hand with Kathy and tell her to back off, I'd suggest finding another venue.
