Everything You Need.
Right Here at Home.

Life is simpler when your city works with you and not through a third party. In Castlewood, residents work directly with city departments and elected officials who care deeply about the community’s future.

Located just 15 minutes from Watertown, Castlewood offers the perfect balance. Enjoy a quieter lifestyle, raise a family in a strong, supportive school system, and still have easy access to work and amenities nearby.

Here, we take pride in raising not just students, but a village of Warriors. From our 9-hole golf course and state-of-the-art wellness center to reliable water, sewer, and garbage services, Castlewood offers everything you need, with heart.

Growing Thoughtfully for the Future

Castlewood continues to look ahead with a focus on responsible development and long-term sustainability. We are actively exploring expanded housing opportunities, including options for senior living, while supporting economic growth and strengthening our local businesses.
