Teignmouth (, ) is a town in Devon, South West England. It is built on the north bank of the mouth of the River Teign. In 1690, it was the last place in England to be invaded by a foreign power. The town was once a fishing port. Fishermen used to fish for cod in Newfoundland. In the Georgian period, it became a popular place to stay. The town grew more with the opening of the South Devon Railway in 1846. Today, its port is still working and the town remains a popular seaside holiday location.
