  The Cherenkov Telescope Array (CTA) observatory, will be deployed over two
sites in the two hemispheres. Both sites will be equipped with four Large Size
Telescopes (LSTs), which are crucial to achieve the science goals of CTA in the
20-200 GeV energy range. Each LST is equipped with a primary tessellated mirror
dish of 23 m diameter, supported by a structure made mainly of carbon fibre
reinforced plastic tubes and aluminum joints. This solution guarantees light
weight (around 100 tons), essential for fast repositioning to any position in
the sky in <20 seconds. The camera is composed of 1855 PMTs and embeds the
control, readout and trigger electronics. The detailed design is now complete
and production of the first LST, which will serve as a prototype for the
remaining seven, is well underway. In 2016 the first LST will be installed at
the Roque de los Muchachos Observatory on the Canary island of La Palma
(Spain). In this talk we will outline the technical solutions adopted to
fulfill the design requirements, present results of element prototyping and
describe the installation and operation plans.
