Cologne Cathedral construction completed after 632 years

The construction of the Cologne Cathedral, officially known as St. Peter and St. Mary, was completed on October 15, 1880. The process spanned 632 years from the laying of its foundation stone in 1248.

Work on the Gothic structure faced significant interruptions due to the Reformation, financial difficulties, and the Thirty Years' War, leaving the cathedral unfinished for over 300 years. Construction resumed in 1842 following original medieval plans, supported by Prussian state backing. Upon its completion, the cathedral stood 157 meters tall, making it the tallest building in the world until 1884.

The final completion was celebrated as a national event attended by Emperor Wilhelm I. Despite sustaining 14 direct bomb hits during World War II, the cathedral remained standing while much of the surrounding city was destroyed.
