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:
The Baths of Caracalla were the second largest Roman public baths, or thermae, in Rome. It was built between AD 212 and 217, during the reigns of Septimius Severus and Caracalla. They would have had to install over 2,000t of material every day for six years in order to complete it in this time.
The baths remained in use until the 6th century when the complex was taken by the Ostrogoths during the Gothic War, at which time the hydraulic installations were destroyed. The bath was free and open to the public. The earthquake of 847 destroyed much of the building, along with many other Roman structures.
The building was heated by a hypocaust, a system of burning coal and wood underneath the ground to heat water provided by a dedicated aqueduct. It was in use up to the 19th century. The Aqua Antoniniana aqueduct, a branch of the earlier Aqua Marcia, by Caracalla was specifically built to serve the baths. It was most likely reconstructed by Garbrecht and Manderscheid to its current place.
In the 19th and early 20th century, the design of the baths was used as the inspiration for several modern structures, including St George's Hall in Liverpool and the original Pennsylvania Station in New York City. At the 1960 Summer Olympics, the venue hosted the gymnastics events.
