Explore Ottawa's culture, history, and architecture

On June 6 and 7, 2026, join us for the 24th anniversary celebration of Doors Open Ottawa, and pay homage to our city’s history, culture, and stunning architecture!

It’s free, it’s fun, and it’s the perfect way to discover how Canada’s Capital has become the beautiful city it is today.

Whether you choose a virtual or live experience, you will discover the secrets and stories that lie within some of Ottawa’s most interesting buildings by way of still photography, in-depth descriptions, 3D and/or virtual tours, YouTube videos, in-person guided and self-guided tours, and more… so stay tuned!
