Van Buren Post Office, circa. 1879, was originally located on Van Buren Road. It was first established as a post office 3 miles north of Everson on the Milwaukee Rail Road on October 2, 1891. It served as a post office until November 14, 1918. The post office had four postmasters during its history: William Van Buren, Andrew Kirkman, Allen Holstein, and Mary Acikinson.

It was later moved to Berthusen Park in Lynden and, in 1994, was brought to Pioneer Park in pieces. Local Eagle Scouts and the City of Ferndale Park Maintenance Supervisor reassembled the building.

Because there is already a post office in the park, the Van Buren has been renovated and deemed the "First National Bank of Ferndale". Early banking artifacts are on display.
