As you step inside the historic artillery shed, with its enormous windows, sweeping desert views and sun-dappled aluminum boxes, the Marfa hoopla suddenly makes sense. Artist Donald Judd single-handedly put Marfa on the art-world map when he created this museum on the site of a former army post. The grounds and abandoned buildings now house one of the world's largest permanent installations of minimalist art. The whole place is an immersive, breathtaking blend of art, architecture and landscape.
Dedicated art enthusiasts will most enjoy the Full Collection Tour, which takes up most of the day, but the 2½-hour Selections Tour should satisfy most visitors; it spotlights the works of the foundation's four founding artists, including Robert Irwin, whose latest work for the museum, a window-lined structure on the site of a former army hospital, opened in 2016.
If you don't have time for a tour, at least check out Judd's 15 works in concrete spread across the plain just east of the visitor center. These works are open to the public free of charge from 9am to 4:30pm Wednesday through Sunday (check in at the front office before heading out).
