Visitors to Gressenhall Farm and Workhouse will be able to see two new additions at the already popular attraction.
Shamrock, a six-year-old Suffolk Punch mare, and her foal Firenze, who was born on July 10, will be at the museum.
Both are on loan from Neil Syrett, of Attleborough, who has helped train some of the museum's five Suffolk Punches, including Trojan, Bowler, Caspar, Reg and Jimbo.
There are currently fewer than 500 registered Suffolk Punch horses in Britain and they are classified as an endangered animal.
They are listed as critical by the Rare Breeds Survival Trust, which means that numbers of breeding females are less than 300
Different activities will be held at the museum between 10am and 5pm until September 5.
These include experiencing life in the workhouse with enactments and becoming a curator for a day, discovering what happens behind the scenes of the museum.
A harvest day celebration will be taking place this Sunday and the museum will go back in time to the 1940s for the annual Village at War event on August 26 and August 27.
Admission costs �9.10 for adults, �8.10 for concessions, �6.10 for people aged between four and 16. Museum Pass holders can enter for free. Visit www.museums.norfolk.gov.uk
