East Block

The East Block is one of the three buildings on Canada's Parliament Hill, in Ottawa, Ontario, containing offices for parliamentarians, as well as some preserved pre-Confederation spaces.

Built in the Victorian High Gothic style, the East Block is, along with the Library of Parliament, one of only two buildings on Parliament Hill to have survived mostly intact since original construction. Though not as renowned as the Centre Block of parliament, the East Block formerly appeared on the face of the Journey Series design of the Canadian hundred-dollar bill. The East Block is open to the public for tours in July and August.
