Next to the Fishing bastion (Halaszbastya) on the both sides of the stairway there are sets of three warrior statues that were really threatened by the capilar moisture. The restoration expert insisted that before he starts his work HIO-technology^®should be implemented. The permit was issued by the Institute for Protection of Monuments after the staticians assessment and the work was done in 2011. The cut was made between the foundation and the statues and it is entirely invisible.
