The brewery was established in the Danish capital in 1847 by J C Jacobsen.
While much of the company's beer production takes place elsewhere in Denmark, some products are still made on the original brewery site.
If you're heading to Copenhagen as part of a mini cruise around Europe, you should make sure you take the time to tour the Carlsberg Brewery.
Not only does it offer interesting glimpses into the past with its displays of old brewing equipment and explanations of the beer-making process, but it also contains various other fascinating exhibits and artefacts.
For example, you'll be able to see the biggest collection of beer bottles in the world right here at the brewery, including some particularly rare bottles produced by Carlsberg and other beer companies.
The Guinness Book of World Records recorded 16,384 bottles in total in 2007 - and this figure is currently approaching the 20,000 mark.
Elsewhere, the sculpture garden contains an array of artworks collected by Carl Jacobsen, the son of the brewery's founder.
Among these is a smaller version of the Little Mermaid statue that can be seen elsewhere in Copenhagen.
Carl Jacobsen had the original made after becoming infatuated with a dancer who starred in the ballet production of The Little Mermaid and donated it to the city in 1913.
Other highlights include the stables, where Carlsberg keeps its Jutland dray horses.
It was this type of horse that was originally used by the brewery to deliver its products back when it first started operating.
The tour ends in the Jacobsen Brewhouse's bar, where visitors can taste their favourite Carlsberg beer - an experience that is sure to be all the more delightful after finding out all about how it is made and its origins - and buy souvenirs to keep or give to friends.
From here, you can explore the rest of what Copenhagen has to offer - and sample some more Carlsberg products while exploring the city's many pubs, bars and restaurants!
