St. John's Episcopal Church in Georgetown is across O Street from the Hyde-Addison school. The church sits on a hill, straddling O Street and Potomac Street, and was founded in 1796. Francis Scott Key and Thomas Jefferson were founders.
Today the parish hosts both spiritual and social events. Church members go on monthly "field trips" to places of interest like the Newseum and the Franciscan Monastery. Additional activities include an annual picnic, a Christmas greens sale and a monthly movie night. The church's sign, emblazoned with the expression "all are welcome," exemplifies the attitude of the parish towards its neighboring community.
