Cologne Cathedral

The construction of Cologne Cathedral started in 1248; it ranks among the most outstanding examples of Gothic architecture worldwide. Since1996 the cathedral is part of the UNESCO world-heritage.
The church is situated in the heart of the city, surrounded by traffic roads and in the neighbourhood of the railway station. The building materials consist of different types of stone, mainly trachyte, sandstone, shell-limestone and basalt; furthermore the fa├žade has a large amount of stained glass windows. Several internal wooden structures (wooden choir stalls, wooden historical confessionals) and polychromed wooden sculptures are also present. Dependent on their composition the surfaces are more or less heavily deteriorated by air pollution and micro-organisms. This also occurs on the large amounts of stained glass windows. Not only the exterior, also the interior is under environmental stress. Cologne Cathedral is an important site for pilgrims (around 5 million per annum), who lights millions of candles all over the year, next to bringing dust, soil and humidity. As the cathedral houses a wealth of important works of art, the disadvantageous indoor climate causes many serious problems.
