The Niels Bohr Institute (No. 15-17) from 1922 has housed the work of several Nobel Prize-winners. No. 23, roughly from the same time, is the Freemasons' Hall. The Danish branch of the Red Cross has its head office at No. 25–27. The building was built in 1952 and is the former headquarters of Copenhagen County. It has more recently been expanded by COBE Architects.
