Sri Lankans and foreign tourists climb the 80m (600ft) fortress of Sigiriya rock (the Lion Rock) in Sigiriya, north-central Sri Lanka.  The Sigiriya rock, 160km (100 miles) north of Colombo, is a World Heritage site known for frescoes of bare-chested women. The number of foreign tourists visiting Sri Lanka has swelled since the island ended a 37-year separatist conflict with Tamil Tiger rebels in May 2009.
