The Bogoda Wooden Bridge was built in the 16th century during the Dambadeniya era. This is said to be the oldest surviving wooden bridge in Sri Lanka. The bridge is situated at 7 kilometres (4.3 mi) west of Badulla. All parts of this bridge were constructed from wood, including the use of wooden nails as fixing material. The roof tiles show the influence of Kingdom of Kandy. The bridge was built across the Gallanda Oya, which linked Badulla and Kandy on an ancient route.
