Paderborn Cathedral is dedicated to Saint Mary, Saint Kilian and Saint Liborius. Today's cathedral is located in a position that has been occupied by churches for hundreds of years. Charlemagne had a Kaiserpfalz built near the sources of the Pader river. As early as 777 this palace had an attached church. This church, located north of today's cathedral, served as chapel to the court as well as a basis for missionary work among the Pagan Saxons. Rebellious Saxons repeatedly destroyed this first church. After the locals converted to Christianity, the first cathedral was built. Pope Leo III met Charlemagne at Paderborn in 799 and consecrated an altar to Saint Stephen, depositing some relics of that saint in it. The first cathedral of the newly established bishopric was a three-aisled basilica.
A fire destroyed the first cathedral in 1000 AD. Bishop Rethar began with rebuilding, but his successor Meinwerk had the previous work destroyed and started over, building a three-aisled church with a transept and crypt in the east. This (second) cathedral was consecrated in 1015, but destroyed in a city fire in 1058. Meinwerk's nephew, Imad had the cathedral rebuilt on a significantly larger scale (third cathedral). This building, with two transepts, already was very similar to today's cathederal. Today's crypt was built around 1100 AD. Similarly, a chapel to St. Bartholomew, connected to the cathedral, would be built after 1015 by Greek monks. Another fire in 1133 damaged the church, but its core survived. Bernhard I. von Oesede had the building strengthened and extended (fourth cathedral), it was reconsecrated in 1144/45.
In the 13th century, the cathedral was reconstructed, not due to damage but to bring it up to then current artistic and ecclesial standards. Construction likely began at the western end of the building (late Romanesque basilika, before 1220). The nave followed in the form of a hall church in early Gothic style. It was completed in the late 13th century with High Gothic elements.
In the 17th century, Prince-Bishops Dietrich Adolf von der Recke (1601-1661) and Ferdinand von Fürstenberg (1626–1683) replaced the Gothic interior features with Baroque artworks.
Repeated Allied bombing of Paderborn in 1945 resulted in severe damage to the cathedral and the loss of irreplaceable works of art, including all the historic glass windows. On 22 March 1945, fourteen people were killed by a blockbuster bomb in the cloister. Reconstruction took until the 1950s. From 1978-81, a major restoration was undertaken.
The relics of Saint Liborius are kept in the three-aisled crypt, which is one of Germany's largest crypts. Towards the west are the tombs of the Archbishops of Paderborn.
One of the cathedral's, and the city's, most recognisable features is the Dreihasenfenster ('Window of Three Hares'). It depicts three hares in motion, arranged in a triangle. Each hare is shown as having two ears, although only three ears are visible in total. The original 16th century carving can be found in the cloister's inner courtyard, and has been duplicated on numerous buildings and a number of shops throughout the city centre.
References:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
