To provide a particle beam treatment system and a method for renewing facilities of the particle beam treatment system with which the facilities can be renewed efficiently. A particle beam treatment system 1 includes a charged particle beam generation device 2 that generates a charged particle beam Bm, a first irradiation device 4(1) that irradiates the charged particle beam to a predetermined irradiation target, a first beam transportation device 3(1) that transports the charged particle beam from the charged particle beam generation device 2 to the first irradiation device 4(1), and a first vacuum valve 33(1) that is arranged in the first beam transportation device 3(1).
