Millhouse at Philip S. Miller Park

Millhouse at Philip S. Miller Park is a rentable event venue in Castle Rock, Colorado, for couples, businesses and private event planners. It hosts weddings, rehearsal dinners, corporate events, company picnics, retreats and personal celebrations such as birthdays, anniversaries and retirement gatherings.

The 2,300-square-foot facility centres on a spacious great room with floor-to-ceiling windows and high timber beams. Large doors connect the interior with an atrium and seating area, so organisers can adjust the layout to suit the occasion. The venue can accommodate up to 125 guests standing or around 90 seated indoors, depending on the arrangement. Its patio provides additional outdoor seating, with parkland, a pond and waterfalls forming a natural backdrop. Indoor and outdoor ceremony and reception options make the space particularly suitable for weddings.

For event presentations, the great room has a projector and a screen that lowers from the ceiling. A small kitchenette is available for serving food and drinks, with a refrigerator, microwave, sink and worktops. It is not a full-service kitchen, so organisers should plan catering accordingly. The Town of Castle Rock says a guest service representative is on site during events, and setup and cleaning are provided for social gatherings.

Organisers can contact the venue team to enquire about availability and submit a reservation request. The combination of an adaptable indoor room, outdoor space and park surroundings suits both formal occasions and relaxed gatherings.
