This is a regular location for Doors Open, located on Sparks Street, a block south of Parliament Hill, which features prominently in its current use. Built as the main Ottawa branch of the Bank of Nova Scotia in the Beaux-Arts style, it dates to 1924. The building is now one of the annex spaces for the Library Of Parliament, which has turned the interior into an archive, blending older architecture with new infrastructure. It's usually only accessible to Parliamentary staffers, so Doors Open is ideal to have a peek inside.
The visitor first comes into what was the manager's office, and is now a conference room. Period photos of the bank were placed on the table.
Within the interior space, we see the floors of newer infrastructure that house documents on both sides around the open area below. All of that is designed in such a way that it doesn't interfere with the building itself. Staffers were on hand to answer questions about what's done here most of the time.
This staircase leads down to what is today a staff lunch room, but which was, back in the day, the bank's vault. Tomorrow I'll show you a building a short walk away that was once a bank, but is also now converted for government use.
