The wall researcher is a cultural heritage professional whose task is to gain knowledge of the history of an old building on the basis of the investigation of the building itself. Those investigations are necessarily important for the reconstruction and the restoration activities. The wall researcher primarily investigates the walls and searches for the traces of former reconstruction and decorations. As a result of this process, the forgotten or covered values become visible, and following the restoration they are displayed.
The most relevant quality of an experienced wall researcher is logical thinking in addition to cautiousness. Through a simple exercise you can test your hidden wall researcher talent. Try to find out the date of creation of the decorative painting that can be seen on the triumphal arch and the walls of the church. Observe and follow the decorative painting very carefully on both sides of the triumphal arch.
