Kottapuram is a common place name in the Indian state of Kerala. The word Kottapuram means 'the place around a Fort' (Kotta means Fort). Since there are many fortresses in Kerala, the state has many places with a similar name. This particular place gets its name from a fort constructed by Portuguese in 1503. Only relics of the fort is seen as it was destroyed by Zamorin as well as Tipu sultan. The fort is known as Cranganore Fort. The fort is almost ruined now.
