![[Model of the building]](model.gif) |
This model of the building gives a clear idea of its structures.
The dome rotates over a fixed cylindrical part, while inside it two walls
separate the telescope from the lateral lightproof Nasmyth rooms where the
instrumentation is located. A low annex building houses workshops,
laboratories and the control room. The bridge connects the observing floor
to the upper road to permit easy servicing operations.

Five ventilation flaps over the entrance doors help control the air flow in
the dome.

Close-up of the building front side. Aluminium sheets cover the structure
and effectively reflect light to help maintain thermal stability.

To protect the roof from falling ice a stainless steel grid has been
added in the summer of 1997.
