Callahan House & Garden

Callahan House & Garden is a historic venue in Longmont, Colorado, available to hire for weddings, private celebrations, business gatherings and meetings. Built in 1892, the Queen Anne-style Victorian house offers a distinctive setting, with ornate woodwork, stained glass, patterned floors and French-inspired interiors. Outside, the Italian garden features a fountain, gazebo, flowerbeds, mature shade trees and a broad lawn, making it a scenic choice for warm-weather ceremonies and receptions.

Organisers can book the main house, the house and garden together, the garden, an upstairs meeting room or the separate Automobile House. Indoor events on the main floor are best suited to around 30 to 40 guests, while both floors can accommodate up to 75. From late May to October, the garden can host up to 125 guests, with access to the main house. The upstairs meeting room seats up to 36 and has a projector and screen, while the Automobile House offers a smaller, relaxed room that can serve as a wedding-party preparation space.

The venue provides tables and chairs, buffet and cake tables, a DJ table, venue staff and waste and recycling services. Weddings require a preferred full-service caterer, and catering is also required for garden events. The team can share recommendations for caterers and other suppliers, and offers information about photography and DJ packages. Bookings are arranged with the House Manager, who can provide details, discuss wedding packages and arrange a tour. The house is a historic property, so organisers should check the venue’s access, music, catering and event policies while planning.
