The colonists built several western styled forts , mostly in and round the cost of the island . The first to build colonial forts in Sri Lanka were the Portuguese , these forts were captured and later expanded by the Dutch . The British occupied these Dutch forts during the Napoleonic wars . Most of colonial forts were garrisoned up until the early 20th century . The coastal forts had coastal artillery manned by the Ceylon Garrison Artillery during the two world wars . Most of these were abandoned by the military , but retained civil administrative officers , while others retained military garrisons , which were more administrative than operational . Some were reoccupied by military units with the escalation of the Sri Lankan Civil War , Jaffna fort for example came under siege several times . Ancient forts . Sigiriya .
