Regular displays include Symington corsets, including the world-famous liberty bodice, Symington Soups, Table Creams and Pea Flour, the Harboro Rubber Company, Falkner's Boot and Shoe Making Workshop, an 18th-century long case clock made in Harborough, 17th-century toys found in the local church, local archaeology finds and many temporary displays.
One of the most significant Iron Age finds in Britain, the Hallaton Treasure, is the focal point of the displays.
The treasure was discovered near Hallaton in the Welland Valley in 2000 by local community archaeologists and the University of Leicester Archaeological Services.
Other displays are in themed exhibition cases and include a selection from a unique hoard of more than 200 seventeenth-century toys found behind a bricked-up stairwell in St. Dionysius Church in the centre of Market Harborough.
The toys include whip-tops, tip-cats, small balls and sap whistles, and were made from wood, pig's knuckle bones and fabrics, all easily obtainable materials to children who had to make their own toys long before such things were mass-produced.
