The large building on the right is the Optical Shop in which a 200-inch disc of pyrex glass was ground and polished preparatory to being installed in the Observatory on Palomar Mountain in San Diego County. From the observation gallery, which is open to the public, visitors can see the grinding operations in progress and also see work on various smaller mirrors which will be used either in testing the 200-inch disc or in accessory work in the observatory. The arch to the right connects the Optical Shop with the Astrophysics Machine Shop. In the latter building the grinding machines for the 200-inch and the smaller discs were constructed and various pieces of apparatus will be built for use in the observatory on Palomar Mountain. Momuntal concrete building with diamond patterned panels flanked by massive square buttresses. Views from California Blvd. Architect: Goodhue and Associates.
