Cologne cathedral with its two spires 157 metres in height, has been the city's most famous landmark for centuries and the most well-known architectural monument in Germany. It took 632 years until construction of the largest German cathedral was completed. After the laying of the foundations in the year 1248 and making rapid progress initially, construction work gradually came to a standstill. It was only with 19th century romantic enthusiasm for the Middle Ages and the commitment of the Prussian Court that construction work resumed in 1842. In 1880, completion of the cathedral was celebrated as a national event.
