The theme of the event is 'Making History', with activities celebrating Lichfield's creative past and present.
Throughout the course of the two days, heritage venues will throw open their doors for free including St John's Hospital, the Samuel Johnson Birthplace Museum, the church of St Mary's in the Market Square, Lichfield Cathedral, and Erasmus Darwin House.
The heritage weekend coincides with the 306th birthday of Samuel Johnson, one of the greatest literary figures of the 18th century, who most famously compiled A Dictionary of the English Language.
Samuel Johnson statue to be focus of his birthday celebrations
Birthday celebrations commemorating Dr Johnson, who was born in Lichfield in 1709, will take place in Lichfield's main Market Square on Saturday at 12 noon with a wreath placed on his statue and birthday cake given away (while stocks last).
Meanwhile the Samuel Johnson Birthplace Museum will also be offering hands-on activities such as bookbinding, trails and displays.
Market Square will also be the venue for other free activities and entertainment on Saturday including face painting and trails, a craft tent where children can make their own mini well dressing, a performance by Intimate Theatre, a mini Town Crier competition and music from the City of Lichfield Concert Band.
