Oslo Plads

Across the square from the station lies the Den Frie Udstilling building, an exhibition hall that was originally the old Copenhagen Waterworks.

On the corner of Østbanegade at Oslo Plads 12-16 is a large residential and office property in a mansion style, named Glacispalæet ("Glacis palace").

It was erected between 1900 and 1903 by architect Andreas Clemmensen, who also designed similar houses on Stockholmsgade as well as Otto Benzon's villa on the corner Kristianiagade.

From this stone pillar, which was designed by the architect Peder Vilhelm Jensen-Klint and installed in 1925, measures the distance from where the old Østerport stood to various North Sjælland destinations.

There are three other similar zero point stones in Copenhagen: at Nørreport, at Rådhuspladsen and at the end of Torvegade at Christianshavns Vold.
