5 buildings that were built over centuries

Westminster Abbey

English kings and queens have been crowned here since the rule of William the Conqueror (1066-1087). The history of the building itself goes back way further. In the seventh century, it was the location of a church called "West Minster." Starting in 1245, today's church was built on those foundations. The last extension, the two main towers, was completed in 1745 - exactly 500 years later.

Milan Cathedral

It is not only the symbol of Milan, but also the most important work of Gothic architecture in Italy: the Cathedral-Basilica of Santa Maria Nascente, better known as the Milan Cathedral. Its foundations were laid in 1388. Many architects continued its construction before it was completed in 1965. Altogether, the project took 577 years.

Cologne Cathedral

The Cologne Cathedral is a church of superlatives. When it was completed in 1880, it was the tallest building in the world. It was also the largest steel structure of its time, and had the largest free-swinging bell. The cathedral boasts the oldest depiction of a crucified Jesus and the largest choir in Germany. Even its lengthy construction is record-breaking: 632 years.

Crowning Sabikah Hill in Granada, Spain, the Alhambra is one of the world's most important examples of Moorish architecture. The UNESCO World Heritage Site is visited each year by three million people. Given the countless detailed stucco elements and the intricate woodwork of the ceiling, visitors will certainly find that the over 600 years it took to build the "red castle" were well worth it.

No one knows exactly how long it took to build Stonehenge. Researchers believe that the site in southern England was erected in five different building phases, over a period of at least 1,400 years. What remains an even more controversial question is why Stonehenge was actually built in the first place.

Perfectionism, disinterest, extensions: There are many reasons why some buildings take longer than planned to get completed - sometimes even centuries. Here are five impressive examples.

Stress is so unnecessary, according to the most fundamental unwritten law in the Kölsch dialect: "Et kütt wie et kütt!" - it comes the way it comes, the saying goes. And people in the Cologne region tend to apply this literally.

One of the best demonstrations of this is the construction of the Cologne Cathedral. The second-tallest church of Europe is the pride of the city. Over 500 years were needed to complete the prestigious building.

Big and modern

Construction began in 1248 in a euphoric mood. The cathedral was to become the largest building north of the Alps. It was not only to be imposing - 145 meters long and 157 meter tall (475 by 515 feet) - but also a contemporary building in the then modern Gothic style. Some 70 years later, the choir was inaugurated. It was very quickly built, for the time.

Yet the inhabitants of Cologne gradually lost interest in their cathedral. In the 16th century, the Gothic style wasn't as popular. It was the age of the Renaissance and the Reformation, of fractures between the Church and the bourgeoisie. There were fewer pilgrims, which meant less money to continue building the cathedral. In 1560, its construction was stopped.

For the next three centuries, the Cologne Cathedral stood incomplete in the center of the city. The ruin, with its medieval construction crane, became the involuntary landmark of the city.

During the 18th century, the building was even used by French revolutionary troops as a horse stable.

632 years of construction

Finally, like all outdated trends, Gothic came back in style. During the Romantic period, Cologne's inhabitants looked back to the Middle Ages, rekindling their interest for not only the building, but also for its old architectural plans.

In 1880, the Cologne Cathedral was finally completed, 632 years after the corner stone was laid.

Instead of discretely concealing this fact, Cologne proudly underlined it in the cathedral's official document: "To the eternal memory of the largest German cathedral, happily completed after six centuries," it read.
