The two streets constituting Esplanadi are officially named Pohjoisesplanadi (Swedish: Norra esplanaden), the northern street, and Eteläesplanadi (Swedish: Södra esplanaden), the southern street. They lead from Erottaja Square to the Market Square (Kauppatori), and Pohjoisesplanadi Street extends along the border of the Market Square up to the Katajanokka Channel. Parallel to Pohjoisesplanadi, a little northwards, is Aleksanterinkatu.
The park was originally opened in 1812.
The very big green park area between the two streets is very active in summer, when many Helsinkians come to hold picnics in the park. There are also numerous live music performances on a special outdoor stage in the park. There is a statue of Johan Ludwig Runeberg by his son Walter Runeberg in the park.
