The Cherenkov Telescope Array (CTA) project aims to create the next generation Very High Energy gamma-ray telescope array. It will be devoted to the observation of gamma rays over a wide band of energy, from 20 GeV to 300 TeV. Two sites are foreseen, one in the northern and the other in the southern hemisphere, allowing the viewing of the whole sky. The southern site will be equipped with about 100 telescopes, composed of three different classes, Large, Medium and Small Size Telescopes, covering the low, intermediate and high energy regions, respectively. The energy range of the Small Size Telescopes (SSTs) extends from 1 TeV to 300 TeV. Among them, the Gamma-ray Cherenkov Telescope (GCT), a telescope based on a Schwarzschild-Couder dual-mirror optical formula, is one of the prototypes under construction proposed to be part of the southern site of the future Cherenkov Telescope Array. This contribution focuses on the mechanical structure of this telescope. It presents the mechanical design and discusses how this in the context of CTA specifications. It also describes recent developments in the assembly and installation of the opto-mechanical prototype of GCT on the French site of the Paris Observatory.
