A rockfall protection system (1) is provided between an uphill side (BS) and a downhill side (TS) of a mountain slope (B), having a plurality of upright and spaced supports (2 to 6), each featuring a support head (7 to 11), a catch net (12), an upper support cable (13) guiding an upper edge (18A) of the catch net (12) at the support heads (7 to 11) of the supports (2 to 6), an upper central cable (15) and a lower central cable (16) guiding the catch net (12) in a central support area (14) of the supports (2 to 6), a lower support cable (17) guiding a lower edge (18B) of the catch net (12). The lower support cable (17) is guided on the mountain slope (B) together with the lower edge (18B) of the catch net (12) on the downhill side of the supports (2 to 6) and separated from said supports (2 to 6). The lower central cable (16) is tensioned on the mountain slope (B) using side anchors (20) provided with braking elements (19), with the braking element (19) being connected at one of its ends (19A) to the side anchor (20) and at its other end (19B) to the central cable (16) by a cable loop (21). The side anchor (20) is connected to the central cable (16) via a predetermined breaking point (22).
