About
Grantham Museum is the principal museum for the historic market town of Grantham and the surrounding area of South Lincolnshire. Housed in a Georgian building on St Peters Hill, the museum preserves and interprets the remarkable history of a community that has been home to two of the most influential figures in British history — Isaac Newton and Margaret Thatcher — while documenting the full breadth of local life across the centuries.
The museum's most celebrated element is its permanent gallery dedicated to Margaret Thatcher, who was born above her father's grocery shop in Grantham in 1925 and grew up in the town before going to Oxford and ultimately entering politics. As Britain's first female Prime Minister and one of the most consequential political leaders of the twentieth century, Thatcher's Grantham origins are a source of significant local pride and historical interest. The gallery explores her early life and the town that shaped her, displaying personal effects, documents, photographs, and materials relating to her extraordinary political career. Whatever one's political views, the gallery provides a fascinating window into the background of a world-historical figure.
Equally significant is the museum's coverage of Isaac Newton's Grantham connections. Newton was born at Woolsthorpe Manor a few miles south of Grantham, but it was at The King's School in Grantham that he received the education that laid the foundations for his scientific revolution. The museum explores Newton's schooldays in Grantham — including the lodgings he is said to have occupied with the local apothecary — and contextualises his extraordinary scientific achievements within the town's history.
Beyond these headline stories, the museum covers the full sweep of Grantham's history — from prehistoric and Roman settlement in the area, through the town's importance as a coaching stop on the Great North Road, to its Victorian industrial growth as a centre of engineering and agricultural machinery manufacture. The town's Civil War history, when it changed hands several times between Royalist and Parliamentarian forces, is also documented in the collections.
The museum is operated by South Kesteven District Council and provides a welcoming, well-interpreted introduction to this historically rich corner of the East Midlands, with collections that reward both the casual visitor and the dedicated researcher.

Highlights
Margaret Thatcher Gallery
Grantham was the birthplace and childhood home of Margaret Thatcher, Britain's first female Prime Minister and one of the most consequential political leaders of the twentieth century. Born in 1925 above her father's grocery shop, Thatcher grew up in the town and attended Kesteven and Grantham Girls' School before going to Oxford.
The museum's permanent gallery covers her early life and the town that shaped her, displaying personal effects, photographs, documents, and materials relating to her political career.
Whatever one's views, the gallery provides a fascinating portrait of an extraordinary life's beginnings.
Isaac Newton and The King's School
Isaac Newton, born at nearby Woolsthorpe in 1642, received the education that laid foundations for his scientific revolution at The King's School, Grantham. Newton lodged in the town during his schooldays — famously in the house of an apothecary — and it was during his time in Grantham that his extraordinary intellectual gifts first became apparent.
The museum explores Newton's Grantham connections, contextualising his schooldays within the town's history and explaining how the boy from Woolsthorpe became one of the greatest scientists who ever lived.
Combined with a visit to Woolsthorpe Manor, this provides a complete Newton pilgrimage.
Civil War History
Grantham was a significant theatre of the English Civil War in the 1640s, changing hands repeatedly between Royalist and Parliamentarian forces during the conflict. Oliver Cromwell's forces fought engagements in and around the town, and Grantham's position on the Great North Road made it strategically important to both sides.
The museum's Civil War collections include weapons, documents, and accounts of the fighting and occupation that the town endured, placing Grantham's experience within the broader context of the national conflict that transformed British political history.
Prehistoric and Roman Archaeology
The museum holds significant archaeological collections from prehistoric and Roman activity in South Lincolnshire.
The area around Grantham was settled from the Mesolithic period onwards, and Roman finds from roadside settlements, farmsteads, and military sites document the intensity of Roman occupation along the road that would later become the Great North Road. Pottery, coins, tools, and personal ornaments from local excavations are displayed alongside contextual information about life in Roman Lincolnshire — a period that shaped the region's landscape for centuries.
