Søndermarken features 3 underground cisterns which used to be part of Copenhagen's earliest water supply system.

In the 1920s, Danish-Americans in the United States conceived the idea to erect a memorial in Copenhagen as a counterpoint to the traditions surrounding Rebild Hills celebrations in Jutland.

After prolonged discussions, it was ultimately decided that the monument should be a mound, with an embellished inner chamber, placed in Søndermarken.

Around $12,000 was collected and the monument was inaugurated in 1925 with a ceremony attended by 40,000 people, including the entire Danish royal family.

At the zoo end stands a statue of Adam Oehlenschläger, one of the central persons of the Danish Golden Age.

It is designed by Julius Schultz and was originally located at the site of the current Frederiksberg Town Hall Square and inaugurated on 24 October 1897.
