Grangemouth is a small town which lies a short distance to the east of Falkirk. Based on the banks of the Firth of Forth the area was a very busy port in the 18th century but over the years is now primarily focused on the petrochemical industry. The town is twinned with La Porte, Indiana and Créteil, Île-de-France, France as part of the Falkirk council area.
