Abstract
Thanks to their large reflectors and improved photon collection efficiency, the Large-Sized Telescopes (LSTs) of the Cherenkov Telescope Array (CTA) target the lowest gamma-ray energies observable from the ground, down to 20 GeV. A four LST sub-array is currently under construction at the CTAO-North site of La Palma (Spain). The first LST, LST1, in fact was already inaugurated in 2018. I report on the progress of the LST project in general and review the early science that LST1 is delivering during its commissioning phase.
