Jaffna Fort is a fort built by the Portuguese at Jaffna, Sri Lanka in 1618 under Phillippe de Oliveira following the Portuguese invasion of Jaffna. The fort is located near the coastal village of Gurunagar. Due to numerous miracles attributed to the statue of Virgin Mary in the church nearby, the fort was named as Fortress of Our Lady of Miracles of Jafanapatão. It was captured by the Dutch under Rijcklof van Goens in 1658 who expanded it. In 1795, it was taken over by the British, and remained under the control of a British garrison till 1948. As the only large military fort in the country, due to the presence of only government and military buildings within its ramparts, it was garrisoned by a detachment of the Ceylon Army. With the onset of the Sri Lankan Civil War it came under siege on several occasions and was the scene of pitched battles. From 1985 to 1995 it was under the control of the LTTE during this time the LTTE destroyed several of key features to stop the Army getting control due to the site being used to stage attacks but it was recaptured by the Sri Lanka Army in 1995 after a 50-day siege during Operation Riviresa.
