«Carlsberg Lighthouse, also known as the Lime Tower after the limestone which is its dominating building material, is a former lighthouse located in the Carlsberg area of Copenhagen, Denmark.
Built in 1883, was originally part of a new main entrance for J.C. Jacobsen's Carlsberg Brewery site in Valby. The brewery had assumed the name Gammel Carlsberg (en: Old Carlsberg) after his son, Carl Jacobsen, due to a controversy between them, had established a new brewery which, with his father's consent, traded under the name Ny Carlsberg (en: New Carlsberg).
The new main entrance was an arch, which incorporated the new name in gilded letters. The gate was connected to the Lime Tower by a wall which was also built in limestone.
Electric lighting had been introduced in the brewery in 1882, at a time when it was still not widely available in Copenhagen. Since the site was also located on high ground, atop Valby Hill, it was decided to combine the guardhouse with a lighthouse.»
