In 1167, a fortress was erected on the location which houses the current Christiansborg Palace. Since then, this event has come to be viewed as the official "birth" of Copenhagen as we know it - and the idea behind the city's 850th birthday this in 2017.
Dating back to sometime during the 13th century, Gammeltorv (literally 'Old Square' in English) certainy lives up to its name.
Established around 1520, Magstræde (along with its twin street, Snaregade) is one of the oldest streets in Copenhagen.
Set in the heart of the city, Rosenborg Castle was constructed in 1606 by King Christian IV. Back then, it was located in the countryside, which should tell you a bit about just how much the city has changed, even if the castle itself hasn't.
The origins of this square can be traced all the way back to 1238. However, it was after 1728, after a major fire, that the square rose again in its current, colourful incarnation.
Among the world's oldest amusement parks, Tivoli plays a special part in the history of Copenhagen - and has done so ever since its opening in 1843.
Copenhagen's current city hall was inaugurated in 1905, and in 1989 it became part of history, and the backdrop of a major victory for the global LGBT+ community, when a gay couple entered into a registered partnership for the first time ever in the world right here.
Today, Christiansborg Palace is still a place where Copenhagen's and all of Denmark's history is shaped, as it now contains both the Danish Parliament, Supreme Court and Ministry of State.
