The Saint Mary Visitor Center in Glacier National Park, with the connected Saint Mary Checking Station and Entrance Station was constructed at the east entrance to the Going-to-the-Sun Road during the Mission 66 park facilities improvement program.

It was designed by Burt L. Gewalt of the Kalispell, Montana architectural firm Brinkman and Lenon, and was completed in 1967.

The complex uses common Mission 66 themes such as native stone, and glulam timber construction, combined with a dramatic roof structure that echoes the mountain peaks in the background.

The complex consists of the main visitor center, with a connected entrance station.

Recent renovations have restored the original teal, ebony and peach color scheme, which had been obscured by the application of standard National Park Service brown paint.
