Market Harborough [SEP] The Old Grammar School
One of the town's most notable features is an unusual former grammar school located in the town centre which stands on wooden stilts. The school room had to be built upon posts to allow the butter market to be held on the ground floor. The school was founded in 1607 and built in 1614, through the generosity of Robert Smyth, a poor native of the town who became Comptroller of the Lord Mayor's Court of the City of London and member of the Merchant Taylors' Company. The subjects taught were Latin, Greek and Hebrew, and many boys were sent to Oxford and Cambridge universities.
