on German cities in the spring of 1942, Rosenheim was not spared. In November 1943 there were shelters for only 650 people for a population of approximately 22,000. However, by February 1944 shelters had been built for about 6400 people and in conjunction with other shelters a total of 10,525 people could be protected. During 14 bomb attacks, 201 people were killed and 179 injured. The focus of the air attacks was the railway station and the railway tracks, as Rosenheim was an important transportation hub between Munich, Salzburg and Innsbruck. The neighbouring communities of Ziegelberg, Stephanskirchen, Westerndorf St. Peter and Oberpfaffenhofen were also hit. The first air attack was on 20 October 1944 at lunch time from 12:47 to 13:17 o'clock with over a hundred aircraft dropping 1,000 bombs, leaving 27 dead and 59 wounded. The heaviest air raid took place on 18 April 1945. From 14:40 to 14:55 around 200 aircraft dropped around 1300 bombs in the area around the station, resulting in 53 dead and 36 injured. This attack also made 800 people homeless. The station building was almost completely destroyed and railway tracks were destroyed over a length of 20 kilometres. The last air attacks were made on 19 and 21 April 1945. During the war the majority of at least 173 unexploded bombs were recovered. In 1964, the Oberbayerisches Volksblatt reported that the approximate location of 38 undiscovered unexploded ordnance was known. Historical timeline Population growth Coat of arms Rosenheim's coat of arms shows a white rose on a red background. The white rose on a red background can be traced back to the former coat of arms of Wasserburg am Inn, as Wasserburg ruled Rosenheim until 1247. The oldest known seal of Rosenheim was built in 1374 and already shows the rose, which has not changed since. The only exception is a picture by Philipp Apian, which was painted around the year 1568 and shows a border around the rose. The city of Rosenheim also has a logo and the same rose from the coat of arms can be found on it. Landmarks and culture Theatre The Kultur- und Kongresszentrum Rosenheim (KU'KO) (Culture and Congress Centre) was built on the site of the brine works, demolished in 1967. Inaugurated on 2 October 1982 as the city hall, now the Rosenheim Culture and Congress Centre has evolved over the years into a national event centre.
