Asymptotic symmetries play a crucial role in gravity, particularly in understanding the behaviour of gravitational systems at large distances. The relevance of asymptotic symmetries has always been central in the quest for the holographic nature of gravity. Recently, this relevance has expanded towards topics in connection with gravitational-wave detections. Asymptotic symmetries improve the accuracy of gravitational waveforms, give an elegant explanation of memory effects, and control scattering amplitude in the infrared regime. I will summarize the fascinating history that led to asymptotic symmetries in gravity, provide a physical intuition of these symmetries, and describe their relevance for gravitational-wave physics.
