The Ben Olsen House is a private, historic residence located in Vader, Washington. The home has been listed on the National Register of Historic Places (NRHP) since 1976. Along with the Grace Evangelical Church of Vader, the home is one of two NRHP-listed sites in the city. The residence was built in the early 1900s for Ben Olsen, a prominent lumberman in the community. The 3,500-square-foot (330 m2) home is considered mostly unaltered and boasts a variety of architectural styles, such as Colonial Revival, Queen Anne, and Victorian. The most notable features are its roofline, large veranda, and a turret. The Ben Olsen House, known locally as "The Mansion", was a symbol of wealth and prosperity during the peak timber years of the town of Vader, then known as Little Falls. The house was the first residence in the community to use electricity. The Ben Olsen House remains the only Queen Anne style architecture home in Vader.

Grace Evangelical Church of Vader, also known as Grace United Methodist Church of Vader, is a historic Methodist church in Vader, Washington. Added to the National Register of Historic Places (NRHP) in 2003, the church is one of two NRHP-listed sites in the city, along with the Ben Olsen House. The church and congregation have undergone several name changes due to mergers between religious affiliations and districts. The most widely used, and current name, Grace United Methodist Church of Vader, has been in existence since 1969. After residents in what was then known as Little Falls formed an Evangelical mission in 1891, the Late Victorian Gothic church was constructed by local craftsmen in 1902. The land was donated, with the express condition the grounds be used to build a house of worship. Open to parishioners of various cultures and heritages, the structure was often too small to accommodate crowds attending services; an annex was built in the 1930s to alleviate the issue. At the time of its national historic designation, the structure was considered slightly altered but remaining mostly true to the overall historic footprint and style of the church. A belfry, altered from remodeling efforts during the Great Depression, is located on the façade and contains an original cast iron bell. Stained glass windows in Gothic style provide light to the sanctuary that features beaver board ceilings and walls. The interior also includes a balcony, a classroom, narthex, and vestibule. Religious services have remained uninterrupted since the church was built. Grace United Methodist Church of Vader is considered as possibly one of the last remaining buildings in Vader that was constructed at the dawn of the 20th century.

Vader is a city in Lewis County, Washington, United States. The community began in the 1870s and was known under several different names during its early years. Vader was most recognizably known as Little Falls, after a waterfall on nearby Olequa Creek, until an official name change to Vader in 1913. The city's moniker has remained an issue, with unsuccessful votes held in the 21st century to convert back to Little Falls. Incorporated under the name of Little Falls in 1906, the early town grew largely out of logging and clay manufacturing at the turn of the 20th century, growing to a population that was reported to have reached as high as 5,000 people, despite census records failing to support the numbers. The city became known as Vader, after an American Civil War veteran and resident, in 1913. In the 1910s, several fires decimated the sawmill and factory industries of the community which led to a decades-long decline to Vader's population and economy. By the 2000s, a lack of funding closed the local school and educational district. In the 21st century, community efforts have been undertaken to rejuvenate the economic conditions of the city. Several projects began to highlight the logging history of Vader as well as showcase historic buildings, such as Old City Jail, and two National Register of Historic Places structures, the Ben Olsen House and Grace Evangelical Church of Vader. Two parks were created and the community has continued to hold an annual May Day Festival, first begun in the 1950s. According to the 2020 census, Vader's population rebounded to a level not recorded since 1910.
