Amargosa Opera House and Hotel, Historic opera house and hotel in Death Valley Junction, US

The Amargosa Opera House and Hotel is a theatre building with an attached hotel in Death Valley Junction, Inyo County, California. The property forms a U shape around a courtyard and connects the performance hall, guest rooms, and arched passages into a single adobe complex.

The Pacific Coast Borax Company built the U-shaped adobe complex, including a recreation hall, in 1923–25 to the design of architect Alexander Hamilton McCulloch. The hall served as a community centre for films, dances and town meetings. After the Tonopah and Tidewater Railroad closed in 1942 the property changed hands repeatedly until Marta Becket rented the hall in 1967 and turned it into a theatre.

Marta Becket rented the recreation hall, then called Corkhill Hall, in 1967 and renamed it Amargosa after the former mining town. She painted murals on the adobe walls and created the sets herself. Performers such as Jenna McClintock later maintained the tradition, and the hall still carries Becket's name for the town.

The complex sits on California State Route 127 at its junction with State Route 190, 27 miles (43 km) northwest of Furnace Creek and five miles southwest of the Nevada line. There is no gas station in Death Valley Junction and the Amargosa Cafe is no longer open, so fill up and stock water before arriving. The hotel operates year-round; the rest of the town is nearly a ghost town.

A magazine sent a team into the desert in 1970 and found a performer playing alone to rows of empty chairs. This discovery made the place known worldwide and brought audiences from many countries to the remote valley.
