Founded in 1955, MVUC is one of the five congregations originally founded in the 1950s as groups who listened to the services of Rev. A. Powell Davies from All Souls Church, Unitarian by telephone until they were able to call their own ministers. The congregation then bought the historic Hollin Hall property in 1958. The church used the existing guest house as their meeting house until 1985 when a newly constructed sanctuary on the church grounds opened. In 1961, the church housed members of the Congress of Racial Equality to train students as freedom riders in the South and the Board of Trustees was threatened with legal action by Fairfax County. Every November for the past 55 years, the church hosts an annual holiday bazaars called the "Holiday Shop," which features dozens of artisans, crafters, and local sellers. The Every Thursday Group quilts and auctions off a new quilt each year, as well as preparing food for sell. Members of the church, including Joan Darrah, lead a successful drive in 2007 to have the UUA issue an Action of Immediate Witness to repeal the United States Policy of "Don't ask, don't tell."
Grounds
The grounds currently include the meeting house, Hollin Hall itself, a greenhouse, a restored windmill, Carriage House, historic turkey sheds, three-tiered boxwood gardens, formal garden, memorial walks, and open spaces and trees. Several other buildings were part of the church's purchase of its portion of the state, but they've been sold or demolished. The windmill, which long been a part of the identity of the church, was partly dismantled in 1962 but a campaign in the 1990s led to it being restored in 2000. Long-time caretaker John Stevens who began in 1926 stayed on when the church bought the property until his retirement in the 1993 and continued to love and maintain the grounds and both Stevens and a minister at the time, Rev. David E. Bumbaugh, spoke out in defense of an old tree just off the property in 1978. In 2007, the church and its property made the local news when The Washington Post featured a story of how a large Paulownia tree was apparently stolen from its grounds, probably on the belief it would be valuable. The church is near the historic Hollin Hills housing development and the church's grounds were part of the inspiration for the production designers of Mad Men and Sex and the City, where they played sports on the grounds and Conway attended the Shakespeare productions hosted by the church on their grounds.
Fort Hunt Preschool began as part of the church in 1962 by a group of parents as a cooperative preschool and continues to lease the Carriage House building since becoming its own organization in 2003.
