Two landscape photographers (Galen and Barbara Rowell's estate and Tom Till) operate brick & mortar galleries which feature their landscape photography. Both are in the United States (Rowell in Bishop, CA and Till's in Moab, Utah). I know there are others, although none come quickly to mind.
Rowell's gallery has featured work other than Galen's, but I don't know if Tom Till's gallery shows work other than his own.
You would probably do a better search by using individual names such as John Fielder, who used to have a real gallery in Denver, Colorado. Michael Fatali has a gallery in Springdale, Utah, David Brookover in Jackson, Wyoming, etc.
