Ratnapura Dutch fort, (Sinhalese: රත්නපුර ලන්දේසි බලකොටුව), was built by the Dutch in Ratnapura, Sri Lanka. The Portuguese had originally constructed a fort at Ratnapura in 1620 however was later captured and destroyed by Kirti Sri Raja Singha (the second Nayaka king of Kandy). By 1658 the Dutch had taken control over all the areas previously controlled by the Portuguese. The Dutch initially used the site of the Portuguese fort but subsequently built a new fort on a hill in the middle of the town.
