Penryn/Penrynn is one of Cornwall's oldest towns and is situated on the Penryn River about one mile northwest of Falmouth on the A39. It was an important religious centre and site of Glasney College, which was torn down during the reign of Edwards VI, the first Protestant Duke, and was one of the triggers for the Prayer Book Rebellion in 1549. Penryn has kept a large amount of its heritage and is designated as a conservation area. Many buildings are listed and date back to Tudor, Jacobean and Georgian periods. Penryn Railway Station has regular trains to Truro and Falmouth.
