Sankili Thoppu

Sankiliyan Thoppu—also known as Cankilian Thoppu or the Poothathamby Arch—is a historic archway located in the Nallur area of Jaffna, Sri Lanka. Believed to have once formed part of the palace facade of the Jaffna Kingdom, the arch now stands as a remnant of the region’s royal past and cultural heritage.

The structure displays architectural features blending local and colonial influences. Constructed of brick and plaster, it has a semi-circular arched opening. Though much of the original palace is gone, the arch remains a symbolic gateway and a focal point of Jaffna’s historic urban fabric.

Visitors approach the arch from Nallur following the Jaffna-Point Pedro Road, arriving at a modest but evocative monument. The site is quiet, allowing contemplative viewing of its inscriptions and structural details. Nearby is a statue commemorating King Cankili II, underscoring the arch’s connection to his reign and legacy.

Declared as an archaeological protected monument in 2007, the arch is accessible year-round and is situated a short walk from Nallur Kandaswamy Temple. The best time to visit is during the dry season when paths are clear and maintenance is simplest.
