Like with many other artefacts from this site, the salty environment is thought to have preserved microbial growth on the staircase and is responsible for its mint condition. However, when in 2014 it was disassembled and brought to the Museum of Natural History in Vienna for a thorough analysis, fungi immediately started to grow on the wood despite attempts to preserve it.

So, in 2015 it was brought back to Hallstatt and is now on display within the “show-mine“.
