About Union Mills Public House

Union Mills Public House is a restored historic knitting factory in downtown Frederick along Carroll Creek, with original brick, high ceilings and a climate-controlled, ADA-accessible indoor venue. Its 3,200-square-foot ballroom can host ceremonies and receptions in the same room, with a separate 2,900-square-foot cocktail room for guests while the ballroom is reset. A creekside patio offers an outdoor option, and a bridal preparation area includes a private room, changing room and lounge. The ballroom offers formal seating for up to 200 guests; the venue also reports capacity for up to 250 in a hybrid cocktail-style arrangement. In-house catering uses an on-site commercial kitchen and customizable menus, with full bar service by venue staff under its liquor license. Venue rentals include tables, chairs, setup and breakdown, and basic staffing; a day-of coordinator is required. Parking options are nearby, and downtown lodging and restaurants are within walking distance.
