One of the city's oldest neighborhoods, Columbia is a wonderful place to call home for nearly 4,000 Bellingham residents. The overwhelming majority of the approximately 1,600 residential structures (5% of total city housing) within this neighborhood are single family. The housing is attractive and well maintained, with narrow tree-lined streets and mature landscaping. The southernmost portion of the neighborhood, identified as the Eldridge Historical District, contains many large, historically significant homes.
