An installation for storing liquified gas in a cavity defined by rock or an outer shell (10) made of concrete, comprising a tank (2) for the gas. The tank (2) which is made of concrete and possibly thermally insulated, is entirely or partly surrounded by a mass (5) filling a void between the tank (2) and the rock or the concrete shell (10). The mass (5) may in itself be sealing, i.e. of low permeability, and may be combined with at least one sealing membrane (13) within the mass (5), or outside or inside the mass. The installation may be located entirely or partly in loose soil (8) which entirely or partly surrounds the shell (10), or be located above ground level.
