Stan kamieniarki w parku Dolina Szwajcarska w Warszawie

Research and observation conducted in 1988 and 1997 determined the state of the masonry in „Dolina Szwajcarska” in Warsaw. The masonry in question is composed mainly of sandstone. The state of the majority of the stone elements is highly unsatisfactory. The basic forms of the damage are considerable: dirty and peeling outer surface layers of the sandstone, salinity, very large missing parts of the stone material, and local gaps in filling in the joints between the stone blocks. Owing to the site of „Dolina Szwajcarska” in the representative part of town, the masonry should be urgently repaired.
