Cologne Cathedral

Cologne Cathedral (Kölner Dom, officially Hohe Domkirche St. Petrus) is a Roman Catholic church in Cologne, Germany. It is the seat of the Archbishop of Cologne and the administration of the Archdiocese of Cologne. It is a renowned monument of German Catholicism and Gothic architecture and is a World Heritage Site. It is Germany's most visited landmark, attracting an average of 20,000 people a day.

Construction of Cologne Cathedral commenced in 1248 and was halted in 1473, leaving it unfinished. Work restarted in the 19th century and was completed, to the original plan, in 1880. It is 144.5 metres (474 ft) long, 86.5 m (284 ft) wide and its towers are approximately 157 m (515 ft) tall. The cathedral is the largest Gothic church in Northern Europe and has the second-tallest spires and largest facade of any church in the world. The choir has the largest height to width ratio, 3.6:1, of any medieval church.

Cologne's medieval builders had planned a grand structure to house the reliquary of the Three Kings and fit its role as a place of worship for the Holy Roman Emperor. Despite having been left incomplete during the medieval period, Cologne Cathedral eventually became unified as "a masterpiece of exceptional intrinsic value"and "a powerful testimony to the strength and persistence of Christian belief in medieval and modern Europe".

When the present Cologne Cathedral was commenced in 1248, the site had been occupied by several previous structures, the earliest of which may have been a grain store, perhaps succeeded by a Roman temple built by Mercurius Augustus. From the 4th century the site was occupied by Christian buildings, including a square edifice known as the "oldest cathedral"and commissioned by Maternus, the first Christian bishop of Cologne. A free-standing baptistery from the 6th century was located at the east end of the Cathedral. The baptistery was demolished to build the old cathedral in the 9th century. Now only the ruins of the baptistery and the octagonal baptismal font remain. The second church, the so-called "Old Cathedral", was completed in 818. This was destroyed by fire on 30 April 1248, during demolition in preparation for a new cathedral.

In 1164, the Archbishop of Cologne, Rainald of Dassel had acquired the relics of the Three Kings which had been taken from the Basilica of Sant'Eustorgio, Milan, Italy by the Holy Roman Emperor, Frederick Barbarossa. (Parts of the relics have since been returned to Milan.) The relics had great religious significance and could be counted upon to draw pilgrims from all over Christendom. It was important to church officials that they be properly housed, and thus began a building program in the new style of Gothic architecture based in particular on the French cathedral of Amiens.

The foundation stone was laid on 15 August 1248, by Archbishop Konrad von Hochstaden. The eastern arm was completed under the direction of Master Gerhard, was consecrated in 1322 and sealed off by a temporary wall so it could be in use as the work proceeded. Eighty four misericords in the choir date from this building phase. In the mid 14th century work on the west front commenced under Master Michael. This work halted in 1473, leaving the south tower complete up to the belfry level and crowned with a huge crane which was destined to remain in place, and a landmark of the Cologne skyline, for 400 years.

Some work proceeded intermittently on the structure of the nave between the west front and the eastern arm, but during the 16th century this ceased.

Work resumed in 1842 to the original design of the surviving medieval plans and drawings, but utilizing more modern construction techniques, including iron roof girders. The nave was completed and the towers were added. The bells were installed in the 1870s.

The completion of Germany's largest cathedral was celebrated as a national event on 14 August 1880, 632 years after construction had begun. The celebration was attended by Emperor Wilhelm I.

The cathedral suffered seventy hits by aerial bombs during World War II. It did not collapse, but stood tall in an otherwise flattened city. The great twin spires are said to have been used as an easily recognizable navigational landmark by Allied aircraft raiding deeper into Germany in the later years of the war, which may be a reason that the cathedral was not destroyed. It has been claimed that in June 1945 American troops used the cathedral as a rifle range.

The repairs to the building were completed in 1956. In the northwest tower's base, an emergency repair carried out in 1944 with bad-quality brick taken from a nearby war ruin remained visible until 2005 as a reminder of the war, but then it was decided to reconstruct this section according to its original appearance. The brick-filling can be seen in the image on the right.

Some repair and maintenance work is constantly being carried out in some section of the building, which is almost never completely free of scaffolding, since wind, rain, and pollution slowly eat away at the stones. The Dombauhütte, which was established to build the cathedral and repair the cathedral, is said to employ the best stonemasons of the Rhineland. There is a common joke in Cologne that the leader of the Dombauhütte, the Dombaumeister(master builder of the cathedral), has to be Catholic and free from giddiness. The current Dombaumeisterin is Barbara Schock-Werner. Half of the costs of repair and maintenance are still borne by the Dombauverein.

On 25 August 2007, the cathedral received a new stained glass in the south transept window. With 113 square meters of glass, the window was created by the German artist Gerhard Richter. It is composed of 11,500 identically sized pieces of colored glass resembling pixels, randomly arranged by computer, which create a colorful "carpet". Since the loss of the original window in World War II, the space had been temporarily filled with plain glass. The archbishop of the cathedral, Joachim Cardinal Meisner, who had preferred a figurative depiction of 20th-century Catholic martyrs for the window, did not attend the unveiling.

In 1996, the cathedral was added to the UNESCO World Heritage List of culturally important sites. In 2004 it was placed on the "World Heritage in Danger"list, as the only Western site in danger, due to plans to construct a high-rise building nearby, which would have visually impacted the site. The cathedral was removed from the List of In Danger Sites in 2006, following the authorities'decision to limit the heights of buildings constructed near and around the cathedral.

As a World Heritage Site, and with its convenient position on tourist routes, Cologne Cathedral is a major tourist attraction, the visitors including many who travel there as a Christian pilgrimage.

Visitors can climb 509 stone steps of the spiral staircase to a viewing platform about 98 m (322 ft) above the ground. The platform gives a scenic view over the Rhine.

On 18 August 2005, Pope Benedict XVI visited the cathedral during his apostolic visit to Germany, as part of World Youth Day 2005 festivities. An estimated one million pilgrims visited the cathedral during this time. Also as part of the events of World Youth Day, Cologne Cathedral hosted a televised gala performance of Beethoven 's Missa Solemnis, performed by the Royal Philharmonic Orchestra and the London Philharmonic Choir conducted by Sir Gilbert Levine.

The design of Cologne Cathedral was based quite closely on that of Amiens Cathedral in terms of ground plan, style and the width to height proportion of the central nave. The plan is in the shape of a Latin Cross, as is usual with Gothic cathedrals. It has two aisles on either side, which help to support one of the very highest Gothic vaults in the world, being nearly as tall as that of the Beauvais Cathedral, much of which collapsed. Externally the outward thrust of the vault is taken up by flying buttresses in the French manner. The eastern end has a single ambulatory, the second aisle resolving into a chevetof seven radiating chapels.

Internally, the medieval choir is more varied and less mechanical in its details than the 19th century building. It presents a French style arrangement of very tall arcade, a delicate narrow triforium gallery lit by windows and with detailed tracery merging with that of the windows above. The clerestory windows are tall and retain some old figurative glass in the lower sections. The whole is united by the tall shafts which sweep unbroken from the floor to their capitals at the spring of the vault. The vault is of plain quadripartite arrangement.

The choir retains a great many of its original fittings, including the carved stalls, which is made the more surprising by the fact that French Revolutionary troops had desecrated the building. A large stone statue of St Christopher looks down towards the place where the earlier entrance to the cathedral was, before its completion in the late 19th century.

The nave has many 19th century stained glass windows including a set of five on the south side called the "Bayernfenster"which were a gift from Ludwig I of Bavaria, a set highly representative of the painterly German style of that date.

Externally, particularly from a distance, the building is dominated by its huge spires which are entirely Germanic in character, being openwork like those of Ulm, Vienna and Regensburg Cathedrals.

One of the treasures of the cathedral is the High Altar which was installed in 1322. It is constructed of black marble, with a solid slab 15 feet (4.6 m) long forming the top. The front and sides are overlaid with white marble niches into which are set figures, with the Coronation of the Virgin at the centre.

The most celebrated work of art in the cathedral is the Shrine of the Three Kings, commissioned by Philip von Heinsberg, archbishop of Cologne from 1167 to 1191 and created by Nicholas of Verdun, began in 1190. It is traditionally believed to hold the remains of the Three Wise Men, whose relics were acquired by Frederick Barbarossa at the conquest of Milan in 1164. The shrine takes the form a large reliquary in the shape of a basilican church, made of bronze and silver, gilded and ornamented with architectonic details, figurative sculpture, enamels and gemstones. The shrine was opened in 1864 and was found to contain bones and garments.

Near the sacristy is the Gero-Kreuz, a large crucifix carved in oak and with traces of paint and gilding. Believed to have been commissioned around 960 for Archbishop Gero, it is the oldest large crucifix north of the Alps and the earliest-known large free-standing Northern sculpture of the medieval period.

In the Sacrament Chapel is the Mailänder Madonna ("Milan Madonna"), dating from around 1290, a wooden sculpture depicting the Blessed Virgin Mary and the infant Jesus. The altar of the patron saints of Cologne with an altar piece by the International Gothic painter, Stephan Lochner is in the Marienkapelle("St. Mary's Chapel"). Other works of art are to be found in the Cathedral Treasury.

The altar also houses the relics of Saint Irmgardis.

Embedded in the interior wall are a pair of tablets on which are carved the provisions worked out by Archbishop Englebert II (1262–67) under which Jews were permitted to reside in Cologne.

The cathedral has eleven church bells, four of which are medieval. The first was the 3.8-ton Dreikönigsglocke ("Bell of the Three Kings"), cast in 1418, installed in 1437, and recast in 1880. Two of the other bells, the Pretiosa (10.5 tons; at that time the largest bell in the Western world) and the Speciosa(5.6 tons) were installed in 1448 and remain in place today.

During the 19th century, as the building neared completion, there was a desire to extend the number of bells. This was facilitated by Kaiser Wilhelm I who gave French bronze cannon, captured in 1870–71, for this purpose. The 22 pieces of artillery were displayed outside the Cathedral on 11 May 1872. Andreas Hamm in Frankenthal used them to cast a bell of over 27,000 kilos on 19 August 1873. The tone was not harmonious and another attempt was made on 13 November 1873. The Central Cathedral Association, which had agreed to take over the costs, did not want this bell either. Another attempt took place on 3 October 1874. The colossal bell was shipped to Cologne and on 13 May 1875, installed in the Cathedral. This Kaiserglockewas eventually dismantled in 1918 to support the German war effort.

The 24-ton St. Petersglocke ("Bell of St. Peter", "Dicke Pitter"in the Kölsch dialect), was cast in 1922 and is the largest free-swinging bell in the world.

Cologne Cathedral has two pipe organs by Klais Orgelbau, the Transept Organ built in 1948 and the Nave Organ built in 1998. Cathedral organists have included Josef Zimmermann, Clemens Ganz (1985–2001) and Winfried Bönig (2001).
