The Belding Museum is located in the historic Belrockton at 108 Hanover Street. The Bel, as it is known by locals, is a designated Michigan Historical Site. Built in 1906, the Belrockton is the last remaining boarding house of the three provided by the Belding Brothers and Company for its single female workers. A major silk manufacturer during the late nineteenth and early twentieth centuries, the company employed hundreds of young women and earned Belding the title of "Silk City of the World". Providing accommodations for one hundred residents and staff, the Belrockton Dormitory, a Classical Revival-inspired building, was erected at a cost of thirty thousand dollars. Following the closing of the company's silk mills in 1935, the "Bel" served as a residential training center for the National Youth Administration. In 1943, the building became a recreation center. The city of Belding purchased the structure in 1950 to serve as a community center. In 1987 it became the home of the Belding Museum. The Belding Museum is still up and running, hosting numerous local events.

The Alvah N. Belding Memorial Library is located at 302 E. Main Street, Belding, Michigan. Belding's first public library was organized in 1890 by a group of civic-minded women who were members of the Ladies Literary Club. A meager collection of books, some from personal libraries and some purchased from funds raised through strawberry festivals, 25¢ suppers, and subscription drives, was housed in a room above a store on west Main Street. After the disastrous fire of 1893 swept Main Street, the burned out library was reinstalled in a room over Connell's Drug Store and then later, in an upper room at City Hall. In 1914, upon a suggestion of local businessman Byron Brown, Alvah N. Belding of the Belding & Bros. Company, Silk Manufacturers, decided to build and give a library to the City of Belding. On March 21, 1917, the Belding City Council accepted his offer and agreed to maintain the building in like beauty and form as a library for all time.

Belding Area Schools operates public schools.

Belding is also the home of the Gus Macker 3 on 3 basketball tournament. At its peak, Belding's population would swell to approximately 100,000 temporary 'residents' during Macker weekends.
