St Modan's High School in Barnsdale Road, St Ninians was officially opened by Archbishop McDonald of St Andrew’s and Edinburgh on 5 September 1933. The school was built to serve the secondary pupils of Stirlingshire, Bannockburn and Cowie.
It opened with a roll of 410 pupils and was one of the first Catholic Secondary Schools to be built in Scotland after the 1918 Education Act. During the war years and afterwards the school continued to grow, reaching its maximum size of over 1200 pupils when the school leaving age was raised to 16 years.
Since the reform of local government in 1996, the school has found itself in the unique position of serving pupils from three local authorities: Clackmannan, Falkirk and Stirling. Over this time, the school roll has settled between 800 and 855.
The school moved to its present site in Stirling in August 2008.
