Province House

This three-story Palladian building in the heart of Halifax has provided a meeting ground for the Nova Scotia House of Assembly since 1819, making it the oldest house of government in Canada and a National Historic Site. Although it still functions as a legislative building, visitors are welcome to take a guided tour. One TripAdvisor user strongly recommends this because "It's free and doesn't take long, they do a good job explaining the customs and history of the government in the region." You can also obtain a visitors pass, which will allow you to sit in on assembly gatherings (when they're in session).

The Province House is sandwiched between the Citadel and the Maritime Museum. Visitors are welcome every weekday between 9 a.m. and 4 p.m. (hours are extended to include weekends between July and August), and admission is free. For more information, check out the Nova Scotia Legislature's website.
