The Marie-Guyart Building in Quebec is the tallest building in the city at 132 meters and has an observation deck on the 31st floor for panoramic views of the city.
The building does not look like a tourist attraction at first glance. It looks like an administrative building from the outside but inside there is an entrance to elevators to the observation deck with 360-degree views of the city at Observatoire de la Capitale.
During Festival dete de Quebec you can also get a great view of the festival grounds from above. The observation deck is open 9-6 most days of the week.
