This window depicts symbols related to the Diocese of Southwestern Virginia, formed in 1919 with Trinity Church an organizing member. It is in the narthex (entry hall) of the church.

The other window in the narthex similarly shows symbols of our former Diocese of Virginia, organized in 1785, of which Trinity was also a founding member.

These windows were made in the Neo-Gothic style by the Wippell-Mowbray Studios in 1970 and were the last to be installed in the church.
