Spean Thma

Spean Thma is a stone bridge in the Angkor region with fourteen narrow arches constructed from sandstone blocks. The structure spans what was once a waterway and demonstrates the technical skill of ancient Khmer builders.

The bridge was built during the Khmer Empire period and underwent restoration in the 15th century. It served as a key connection along trade routes between Angkor Thom and the Eastern Baray.

The bridge shows how Khmer craftsmen precisely fitted stone without using mortar, a technique essential for daily life. This building method allowed people to cross rivers safely and connected different parts of the kingdom.

The bridge is located about 3 kilometers from the main road leading to Angkor Wat. Access is possible but the path can be challenging, especially during rainy seasons when the ground becomes wet and muddy.

The fourteen arches display remarkable uniformity in their dimensions, reflecting the mathematical precision of Khmer design. This consistency allowed builders to create sophisticated water management systems throughout the region.
