Investigation of the Causes of Colour Inconsistency in the Facades of Vrchotovy Janovice Castle

Abstract:

The paper deals with the causes of pronounced colour inconsistency in the facades of Vrchotovy Janovice Castle. The original stone Gothic fortress has undergone a number of reconstructions, the last one taking place in the mid 19th century when the castle acquired its current neo-Gothic, romantic look. At the beginning of the second half of the 20th century the sporadic maintenance of the castle led to a decline in facade quality and the eventual restoration was very insensitive. Major restoration work was carried out on the facades in 2006 but once this was complete, the renewed facades started to show marked colour inconsistency. This paper analyses the causes of these defects with regard to the technological processes applied and sets out possible steps that can be taken to eliminate them.
