On Sparks Street, in the former main Ottawa branch of the Bank Of Nova Scotia, the building hosts an annex of the Library Of Parliament, which is routinely open for Doors Open. The building is in the Beaux-Arts style, and incorporates Canadian themes and symbols in its architecture. It was taken on by the government years ago, renovated, with the space inside a mix of the original architecture and modern archive infrastructure. The Library serves Parliamentarians and their staff, so while it's a block south of the Hill, it fulfills an important purpose for Parliament to run smoothly. This is the only general access that the public get to the building. During this visit, I went into two rooms- the former office of the bank manager, now a comfortable space, and the main interior, where staff were on hand to answer questions. I like the contrast between the architecture and the shelving infrastructure.
