From the reviews

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.

★★★★★ — Anita, Nov 2019

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!

Getting married at City of Longmont Callahan House

City of Longmont Callahan House comes up for weddings — confirmed on their own site. Two things make the tour worth it. First, see the garden at the time of day and season you'd actually get married — a garden that glows at golden hour in June can look very different at noon in March, so ask what's in bloom for your date and walk the path your guests take from parking to ceremony to reception. Second, bring your real questions: the rain plan (where does the ceremony move, and does it hold everyone?), shade and bugs for a summer afternoon, the catering and bar policy, the music curfew, and exactly what's included — tables, chairs, setup, and teardown are where quotes quietly diverge. Popular garden dates book 12–18 months out, so if the tour feels right, ask what's open in your season before you leave.
