(four 8.2-meter optical telescopes in Chile that can act together)

The ESO Very Large Telescope (or just Very Large Telescope or ESO VLT) consists of four 8.2-meter reflector telescopes located at the Paranal Observatory on the Atacama Desert in Chile, operated by the European Southern Observatory (ESO). The four can be used separately or together. They observe at optical and infrared wavelengths. The four, which were completed individually over the years 1998-2000, are:

Among their instruments are:

The term VLTI for Very Large Telescope Interferometer refers to it as an optical interferometer, e.g., when using GRAVITY. It features a 120-meter baseline. The term GRAVITY+ is used for an upgrade project for both VLTI and GRAVITY, but I'm not certain whether it adds or replaces an entire instrument.
