Grantham is a small market town in Lincolnshire, England with about 40,000 inhabitants. Situated on the River Witham, it has the main east coast railway line and the A1 main road from London to Edinburgh running through it. The main local landmark is the impressive parish church of St. Wulframs, which has the third highest spire found among English churches, and is also home to the country's first public library.

Two world famous people are associated with the town: Sir Isaac Newton, who was schooled at the still existing King's School, Grantham, and Margaret Thatcher, who was educated at Kesteven and Grantham Girls Grammar School (K.G.G.S), and was born in the town itself where many inhabitants still remember her.

Politically the town is part of the Grantham and Stamford constituency (recently altered), is represented in Parliament by Conservative Party MP Quentin Davies and has a long history of electing Conservative members of Parliament.

Grantham is home to the world's only 'living' pub sign: A bee hive perched in a tree. The town is also notable for the first female police officer and manufacturing the first caterpillar track.
