The original Westminster Freight Depot was built in 1885, and the railroad contributed to rapid growth and development in the Westminster area. Following incorporation and continued growth, the passenger depot was constructed in 1911, but as railroad passenger travel declined throughout America, Westminster's rail services were cut short, and by 1970 all passenger service was discontinued. The depot underwent several alterations throughout the 20th century, yet the basic integrity of its design remains, including a prominent hip roof with a deep overhang supported by large wooden brackets and twenty-two windows with diamond-shaped panes. It was listed on the National Register of Historic Places on November 7, 1976. After a fire damaged a significant portion of the building in 2008, the depot was renovated and reopened in 2009 as the center for the Chamber of Commerce, and today it serves as one of the town's oldest buildings and a local landmark.
