Galaxy clusters are massive virialized objects, found at the nodes of the cosmic web. These dark-matter potential wells, filled with hot intracluster medium (ICM) plasma, accrete cold gas and galaxies from their surroundings. Clusters were long suspected to be surrounded by strong virial shocks, which heat the gas, accelerate particles, and amplify magnetic fields, although their detection was only established in recent years. I will review the detection of virial shocks around single and stacked clusters, using different wavelengths, and present new methods to trace these shocks.
