Asenova Fortress (Asenova Krepost) is a pretty medieval fortress near Plovdiv. Some evidence shows that the area of Asenova Fortress has been inhabited by a variety of people dating back to ancient times, including the Thracians and Romans as well as the Byzantines.

Whilst it is said t have been mentioned in the 11th century and taken by Crusaders, many of the remains of Asenova Fortress today date to the 13th century when they were rebuilt under tsar Ivan Assen II. Having said this, the most intact aspect of Asenova Fortress is a 12th century church.
