The Sir Mackenzie Bowell Collection is a historically significant collection of porcelain and Canadian silver within the regional collection. These objects belonged to Sir Mackenzie Bowell (1823-1917). Bowell was a prominent Belleville citizen and businessman who served as Prime Minister of Canada from 1894 to 1896. The collection includes:
- Dozens of pieces of Canadian sterling silver flatware and serving utensils;
- A 4-piece silver coffee and tea service;
- 40 pieces of porcelain dinner service.
The silver was a gift to Bowell from Grand Orange Lodge of British North America in honour of his service to them in 1877. The porcelain dinner service was a gift from Queen Victoria upon Bowell's retirement as Prime Minister in 1896.
