It's the City of Brass
The Dungeon Master's Guide (1979) says
(Italics preserved from the original.) This blurb lurks inconspicuously at the bottom of the page after the foreword.
The title page of the Dungeon Master's Guide credits its cover to David C. Sutherland III. While this is likely his most famous piece, Sutherland is also the artist responsible for the original Ravenloft adventure module's brilliant isometric castle cartography.
