Munich Pasing and Munich Hauptbahnhof Climate Olching lies in the transitional zone between the humid Atlantic climate and the dry continental climates. Other significant factors affecting the weather are the Alps, which act as south-central European border, and the Danube, which is a regional meteorological divide. Due to this constellation, the weather in the region is quite changeable. Foehn The so-called foehn is a weather phenomenon particular to the region near to the Alps that occasionally brings warmer and drier air from the south to Olching, potentially occurring at any time of year. This is accompanied by extremely good visibility, in particular the much-clichéd Bavarian blue and white sky, and the Bavarian Alps may be clearly visible, apparently close by, although they are approximately 100 kilometres (60 mi) away to the south. Some people suffer from headaches and circulatory problems as a result of the foehn. History Early records Olching is an old bavarii settlement and was first mentioned in the Early Middle Ages. In 740 the Agilolfingian duke Tassilo II of Bavaria bestowed the town, together with its church and flour mill, to the Benediktbeuern Abbey (the authenticity of this document is contested). The early Gothic church was replaced by the Romanesque basilica St. Peter und Paul in 1903. In 1258 Louis II, Duke of Bavaria founded a monastery as a form of penance for the execution of his wife Maria von Brabant, who had wrongfully been convicted of adultery. This monastery was relocated from Aibling to Olching in 1262. The monastery was relocated to Fürstenfeldbruck only one year later, either due to flooding or structural problems. The Fürstenfeld Abbey owned several estates in Olching until the period of secularization in Bavaria in 1802/1803. Olching suffered severely as a consequence of the Thirty Years' War, particularly after the city of Munich was taken by Gustavus Adolphus of Sweden in 1632. Only nine out of formerly 67 estates remained in Olching after 1648. Developments in the 19th century In 1821 Olching (which had until then been administered by Dachau) was transferred to the newly founded of Fürstenfeldbruck, and in 1823 it also came under the jurisdiction of Fürstenfeldbruck. In 1834 the first school was established in Olching. Until 1839 Olching was still very rural with about 50 farms and approximately 300 inhabitants. This changed with the construction of the railway line between Munich to Augsburg. The line between Munich and
