The Construction Of Cologne Cathedral: A Medieval Marvel

The construction of Cologne Cathedral, a towering Gothic masterpiece in Cologne, Germany, was a lengthy and challenging endeavour that spanned centuries. The site chosen for the cathedral had been occupied by Christian churches since the 4th century, with the latest building, known as the Old Cathedral or Hildebold Cathedral, consecrated in 870 and gradually demolished in 1248 to make way for the new Gothic cathedral. The first foundation stone of the new cathedral was laid by Archbishop Konrad von Hochstaden in August 1248, and construction began on what would become one of the tallest churches in Europe.

The eastern arm of the cathedral was completed and consecrated in 1322, but the project faced numerous interruptions and delays. Construction halted around 1560 due to funding issues and a shift in architectural tastes away from Gothic design. For almost 300 years, the cathedral remained unfinished, with a large wooden crane standing atop the south tower. It wasn't until the 19th century that efforts to complete the cathedral gained momentum, driven by a renewed interest in medieval art and architecture, as well as a growing national movement that embraced the cathedral as a symbol of German unity.

In 1842, King Frederick William IV of Prussia laid a new cornerstone, and architects Ernst Friedrich Zwirner and Richard Voigtel resumed work, faithfully adhering to the original medieval plans. Finally, on August 14, 1880, more than 600 years after it began, the construction of Cologne Cathedral was completed. The cathedral stands as a testament to the enduring strength of European Christianity and the perseverance of those who dedicated themselves to its realisation.

The site chosen for the cathedral had been occupied by Christian churches since the 4th century

The site chosen for the construction of the Cologne Cathedral had been occupied by Christian churches since the 4th century. In the early days of Christianity in Cologne, the small Christian community gathered in a residential building, which is thought to have been located on the cathedral hill below today's choir. After the collapse of Roman rule on the Rhine, the Merovingian kings built an episcopal church on the site in the 6th century. This building, probably constructed by King Theudebert I, served as a burial place for the royal family.

In Carolingian times, the Old Cathedral was built on Cologne Cathedral Hill and consecrated in 870. Known as the Hildebold Cathedral, after Bishop Hildebold, it was one of the largest Carolingian churches ever built and became the architectural model for numerous churches in the early Holy Roman Empire. The Hildebold Cathedral was built in the Carolingian tradition as a basilica with two choirs, dedicated to Mary, the mother of Jesus, and Saint Peter.

On July 23, 1164, the Archbishop of Cologne brought the bones of the Three Wise Men to the city, which became an internationally renowned place of pilgrimage. To accommodate the pilgrims, a new Gothic cathedral was planned. Construction of the present-day Cologne Cathedral began in 1248, after the previous cathedral was destroyed by fire. The new cathedral was designed in the Gothic style, emulating French church architecture.

Construction began in 1248 but was halted around 1560 due to a loss of funding and interest in Gothic architecture

Construction of the Cologne Cathedral began in 1248, but it wasn't the first building on that site. The ground had been occupied by Christian churches since the 4th century. An older cathedral, known as the "Old Cathedral" or "Hildebold Cathedral", was destroyed by fire in 1248, and work on the new cathedral commenced immediately after.

The new cathedral was designed in the Gothic style, emulating French church architecture. The first foundation stone was laid by Archbishop Konrad von Hochstaden in August 1248. The eastern arm was completed under Master Gerhard and was consecrated in 1322. Construction continued until around 1560, when it was halted due to a loss of funding and a decline in interest in Gothic architecture.

By the end of the 15th century, building activity had slowed significantly, and the last known cathedral architect, Johann Kuene van Franckenberg, was last mentioned in 1491. Work on the cathedral was discontinued in stages from 1510, and recent research suggests that construction was largely halted by 1530, despite money still being available for equipment and repairs.

The project stalled for almost 300 years, until the 1840s, when there was a push from the public and the Protestant Prussian Court to finish the cathedral. With funding from the city, citizens, and government organisations, construction finally resumed in 1842.

Attempts to restart construction over the next 300 years were largely unsuccessful until the 1840s when there was a push by the public and the Protestant Prussian Court to finish the cathedral

Construction of the Cologne Cathedral began in 1248 but was halted in the years around 1560, unfinished. Attempts to complete the construction began around 1814 but the project was not properly funded until the 1840s.

In the 1840s, there was a push by the public and the Protestant Prussian Court to finish the cathedral. With the power of the city and its citizens, as well as government organisations, funding was raised and construction was restarted in 1842. The first new foundation stone of the restarted build was laid by King Frederick William IV.

The relaunch of the building was still in line with the original plans and blueprints. Architects Ernst Friedrich Zwirner and Richard Voigtel took ownership of the process and did not alter much from the original plans. They respected the original designs and finished the work that Gerhard of Reil, a stonemason who took inspiration from other cathedrals across Europe, started.

The cathedral was finally completed in 1880, following the original medieval plans but using modern construction techniques

The completion of the Cologne Cathedral in 1880 was a massive feat of engineering and a testament to the enduring strength of European Christianity. The cathedral, which stands at 157 metres (515 feet) tall, is the second-tallest church in Europe and has the largest façade of any church in the world. Its construction began in 1248 but was halted around 1560, remaining unfinished for almost 300 years.

The cathedral's completion was a massive undertaking that required innovative engineering solutions. The nave was completed, and the towers were added, with the bells installed in the 1870s. The largest bell, known as St. Petersglocke, was cast in 1922 and is the largest free-swinging bell in the world. The interior of the cathedral is equally stunning, featuring some of the highest walls of any church in the world. The ceiling showcases the artistry of the builders and their construction ingenuity.

The completion of the cathedral also involved restoring and preserving the medieval parts of the structure. All the medieval sections of the cathedral were built using trachyte from Drachenfels, while the 19th-century builders employed sandstones. The use of different types of rock has presented ongoing conservation challenges due to varying degrees of weathering. The iron anchors and dowels holding the architectural decorations together are also rusting and need to be replaced with steel parts.

The interior of the cathedral features some of the highest walls of a church in the world, with an emphasis on high ceilings and light-filled spaces

The interior of the Cologne Cathedral is as stunning as its exterior. It features some of the highest walls of any church in the world, with an emphasis on high ceilings and light-filled spaces. This emphasis on height and light is a reflection of the deity the cathedral worships.

To achieve this, the architects and designers had to innovate. They created large vaulted ceilings, large stained-glass windows, and pointed arches that allowed for more light and reduced the load on the structure. They also added flying buttresses to support the high walls and ceilings. These innovations led to many of the design features we see in modern buildings.

The interior of the cathedral is characterised by its many treasures, including the High Altar, which was installed in 1322 and is made of black marble. The Shrine of the Three Kings, created by Nicholas of Verdun, is another famous installation. The nave, with a length of about 120 metres, was built over seven centuries in five construction epochs. Despite this, it has a strictly uniform, High Gothic form, and all later master builders stuck closely to the original plan.

The entire architecture of the Cologne Cathedral is designed to accommodate the largest possible windows. In fact, the cathedral has been described as an "exceedingly harmonious glass house". The windows cover an area of about 10,000 square metres, which is approximately the footprint of the building. Of all the great cathedrals, Cologne has the largest window area in proportion to the length of the church. About 1,500 square metres of the window area dates from the Middle Ages.
