Kunc Koprusu is a bridge in Amasya province expanded over Yesilirmak River and joins the district of Bayezitpasa and Samlar. The bridge was constructed by the Hundi Hatun, daughter of the Seljuk Ruler Sultan Masood ΙΙ. 

This bridge was totally built using bricks and cut stones in accordance with Seljuk architecture. The wide road of the bridge is lying on three huge arches standing in the river. Kunc Koprusu is an ancient landmark in Amasya Province and initially it was named as Hundi Bridge on the name of Hundi Hatun. 

Sometime later, local people named it Kundi Bridge instead of Hundi Bridge and finally the word Kundi is replaced by the Kunc. Kunc Koprusu is also known as the Bird Bridge.
