The Historical Museum is housed in the lower floor of the old Post Office building, and is devoted to the history of the Saanich Peninsula and the town of Sidney-by-the-Sea. Photographs explore the stories of settlers such as the Brethour brothers, and the Roberts family, while brickmolds and egg crates create connections with Peninsula businesses of the past. Insight into turn of the century domestic life is given with displays such as "Critchley's Store", "the Classroom" and "The Kitchen".
