The Cherenkov Telescope Array (CTA) observatory aims at increasing the sensitivity of ground-based gamma-ray (GeV/TeV energies) observatories by a factor >10 compared to current facilities, to extend the accessible gamma-ray energies from a few tens of GeV to a hundred TeV, and to improve on other parameters like the energy and angular resolution. Sensitivity at the lowest possible energies is important for a variety of key physics goals, like the observation of distant active galactic nuclei or gamma-ray bursts, but also for measuring pulsar cutoffs. For this aim, CTA will incorporate a number of central large-size telescopes (LSTs of 23 m diameter). In this presentation, design considerations and the status of the LST prototyping will be reported.
