Birkelunden park is one of the most popular parks in Oslo. The park was laid out in the 1860s, and is located in the upper part of Grünerløkka between Paulus church and Grünerløkka school.

On Sundays all year round, there is a bric-a-brac market in Birkelunden. The park has a music pavilion from 1926, and is often used for concerts, rallies and festivals. There is also a small park pool, from 1928.

The blocks around Birkelunden mainly consist of 3- and 4-story apartment buildings from the 1870s and 1880s. This area is intact with same-style buildings from the same period, and it was therefore decided (by the King in Council in 2006) to protect it. The area that is protected consists of 15 blocks with 139 apartment buildings, the Paulus church the Grünerløkka school and Birkelunden park.
