In 1910 they were relocated to the State Library and Supreme Court building in Hartford where they are housed today.

The Museum of Connecticut History consists of Memorial Hall, a magnificently restored Beaux-Arts style gallery, and three adjoining exhibit areas.

Architects Donn Barber of New York and E. T. Hapgood of Hartford envisioned a design based on an adaptation of the Italian Renaissance style of architecture.

The design includes three wings off a central lobby, the State Library on the left, Memorial Hall in the center and the Supreme Court on the right.

Construction began on October 23, 1908, with Marc Eidlitz & Son of New York as the builder and general contractor.

The library building was listed on the National Register of Historic Places in 1981, recognizing both its architecture and its significance as a repository of state history.
