Lenishte (Bulgarian: Ленище) is a village in Ardino Municipality, Kardzhali Province, southern-central Bulgaria.

The bridge has remained unchanged for centuries and features a unique hexagon shape on its arch known as "The Sea; of Solomon."

Built in the 10th century, this fort was designed to defend the area around the Arda River and still shows parts of its original walls and towers.

Along the left bank of the Borovitsa River, on a rocky outcrop, lies the Patmos Fortress.

Dating from the 10th century, it features a largely preserved western wall and archaeological finds include parts of a basilica and a tower.
