Trethewey House Heritage Site is currently undergoing site remediation work. Please watch this space for updates. Thank you!

  • Trethewey House will be CLOSED until October 13th, 2023.
  • The Heritage Gallery is officially OPEN again for visitors.

Our new permanent exhibit,

"The River People and the Land: Living within S’ólh Téméxw"

is now open for drop-in visits at our Heritage Gallery at Trethewey House. 

“We are Stó:lō. We are the river people. We have lived with this land for as long as we can remember. The land that you call the Fraser Valley, the Lower Mainland, the Fraser Canyon, we call home. We moved freely across this land, from mountain to mountain, and from river to river. For thousands of years, this land was our family; this land was our home.”

The Stó:lō people live along the Fraser River and have a rich history with the land. The River People and the Land: Living within S’ólh Téméxw exhibit showcases the relationship between people, the land, and what is essential for the survival of human beings. But what would you do without your land, your home?

The exhibit details about how the Stó:lō have been impacted by European colonization. The loss of land by way of the reservation system has negatively affected the Stó:lō. Within this exhibit, contemporary Stó:lō members are looking to move forward and reclaim what is rightfully theirs.

Sumas Lake: A Quick Look at a Long History

Sumas Lake was and is very important to the Stó:lō peoples, especially the Semá:th. For them, the lake was a source of food, a place to live, a watery highway, and a place which featured in oral histories. Fish and waterfowl were abundant and provided an easy and varied source of food. The lake was large, approximately 10,000 acres, but during the spring freshet (May to July), it often expanded to three times that size.

Trethewey House Heritage Site

Trethewey House was built in 1919 for B.C. lumber baron Joseph Ogle “J.O.” Trethewey. President of the Abbotsford Lumber Company, J.O. was responsible for leadership of the company during the company’s boom years in the 1920s.

The House is built in an “arts and crafts” style and is constructed using primarily local materials, making it distinct from other buildings of similar age within the City of Abbotsford. Trethewey House contains old-growth Abbotsford fir lumber (processed at the Trethewey mill on Mill Lake), and bricks and tile crafted from clay mined on Sumas Mountain (processed at Clayburn Village, B.C.’s first company town), representing two of Abbotsford’s most important early industries.

Trethewey House has undergone extensive restoration work and has been restored to circa 1925 by the Heritage Abbotsford Society, with the help of local families and assistance from the Province of British Columbia through British Columbia Arts Council and Direct Access Gaming. Trethewey House was designated a municipal heritage site in 1983.
