From the hillstead.org website description:

Immerse yourself! Whether visiting individually or as part of a group, you will want to spend at least an hour-and-a half savoring the art, architecture and landscape that make up the Hill-Stead experience. To view the art, plan to spend 50 minutes on a guided tour, offered every half-hour.

Your visit begins as you approach the 1901 Colonial Revival house through an allée of stately maple trees. First, stop at the Orientation Gallery to view a 13-minute video and a photo-essay about Hill-Stead’s 100-plus years of history. Then enjoy a guided tour of 19 intact period rooms filled with art and antiques, exhibited in situ. Before leaving, make sure to admire the Beatrix Farrand-designed sunken garden, stroll the Warren Manning-inspired grounds, or browse the museum shop for gifts and books.

Return again to walk Hill-Stead’s woodland trails or participate in one of the museum’s many programs and activities.

Theodate Pope, Connecticut's sixth licensed female architect, designed this 36-room, 33,000- square-foot house as a retirement home for her parents, Alfred Atmore Pope and Ada Brooks Pope. Completed in 1901, Hill-Stead is one of the country's finest examples of Colonial Revival domestic architecture.
