The borough has its name from St. Hanshaugen Park that lies centrally within it, where the citizens used to celebrate summer solstice ("St. Hans" in Norwegian). The park was planted by the city in the years 1876-86; it has a pavilion, and a reflecting pool covering a reservoir. The neighbourhood St. Hanshaugen is located west and south of the park, with shopping, eating and public transport where the streets Ullevålsveien and Waldemar Thranes gate meets. There is also the traditional restaurant Schrøder, known for one of its regulars, Jo Nesbøs fictional figure Harry Hole.
