There are buildings you walk past, and then there are buildings that stop you cold. Terrace Hill, the grand Italianate Victorian mansion perched on a gentle rise just west of downtown Des Moines, is firmly in the second category. From the moment its towering cupola comes into view above the tree line, you get the distinct feeling that something extraordinary is waiting for you inside — and it absolutely is.
Built in 1869 for Benjamin Franklin Allen, Iowa’s first millionaire, Terrace Hill is one of the finest examples of High Victorian Italianate architecture anywhere in the United States. It has served as the official residence of Iowa’s governor since 1976, which makes it a living, breathing piece of civic history rather than a roped-off relic. That distinction matters. When you walk through these rooms, you are walking through nearly 160 years of Iowa life, ambition, and character.
The mansion sits in the Terrace Hill neighborhood on Grand Avenue, an easy drive or rideshare from the Court Avenue entertainment district. Guided tours run Tuesday through Saturday from March through December, and they are genuinely worth every minute. Knowledgeable docents lead small groups through the main floor, sharing stories about the families who lived here, the craftsmen who built the intricate woodwork, and the ongoing restoration efforts that keep the place looking impeccable. The original black walnut staircase alone will make you reach for your phone to take a photo.
What surprises most first-time visitors is the sheer warmth of the place. Terrace Hill does not feel like a museum that is quietly judging you for touching things. The rooms are furnished with period-appropriate pieces, many of them original to the house, and the staff clearly love sharing the details — the hand-painted ceilings, the ornate fireplace mantels, the way afternoon light pours through the tall arched windows and turns the whole parlor amber.
Outside, the grounds are just as rewarding. The carriage house has been carefully preserved, and the sloping lawn offers one of the better views of the Des Moines skyline you will find anywhere. In spring and early summer, the gardens are in full color and make for a genuinely lovely stroll before or after your tour.
Admission is modest — just a few dollars for adults, less for children — and the experience punches well above that price point. Whether you have lived in Des Moines your entire life or you are visiting for a long weekend, Terrace Hill has a way of making Iowa history feel personal and alive. Do yourself a favor and put it on the itinerary. You will leave with a much richer sense of this city and a full camera roll to prove it.
