Kenh and Nanh Trees of Cu Lao Cham

Two trees of different species have grown into one roof over this temple yard. On Cu Lao Cham, an island about 15 kilometres off Hoi An, a Kén and a Nánh stand on either side of the yard of the swiftlet-nest guild temple, the shrine of the island's trade in edible bird's nests, and their crowns have knotted together overhead. In April 2015 they were recognised as Vietnam Heritage Trees by VACNE, the national nature association, one of four heritage groups on the island. The press gives both about 200 years, or over 200; a tour operator's guide adds the measurements. The Kén, on the right-hand corner, is about 18 metres tall and 2.89 metres round at chest height. The Nánh, on the left, is about 16 metres and 1.94 metres round. Neither is a giant. Together they make the yard a room. That room gets used. Thanh Nien reported in 2024 that villagers gather under the trees most evenings, which is a better test of a shade tree than any measurement. The island is a UNESCO biosphere reserve and a boat trip from Cua Dai pier, not a walk from the old town, so check the crossing before you plan the day. From the landing it is a short walk or ride along the island road to Bai Huong, the fishing hamlet where the temple stands. Cu Lao Cham also has a banyan said to be over 600 years old on the slopes of Hon Lao.
