Prusias Ad Hypium Ancient City Prusias ad Hypium is an ancient settlement situated in the Konuralp District of Düzce. Originally, it was known as Hypios and was founded on a ridge stretching from east to west, ending in a flat plain. Over time, the city became known as Kieros. During the 2nd century BC, the Bithynians under their ruler Prusias I took control of Kieros from the Mariandyns and the Herekleia State. Prusias I enhanced the city by erecting numerous monuments, strengthening its defenses, and renaming it Prusias. The ancient theater of the city, locally called the Forty Steps, was constructed in the Hellenistic Era (300-30 BC) and later expanded during the Roman Period (30 BC-300 AD). The Kemerkasim Aqueducts stand out as another important landmark of the city. Today, eleven support pillars from the ancient water system remain intact. Constructed from rubble stone, the aqueduct is believed to have supported water channels above it. The primary gateway to Prusias ad Hypium is known as the horse gate. This entrance has been restored multiple times using recycled materials. A distinctive element is the limestone lintel that features an image of a horse along with a Greek inscription. Also notable is the Roman Bridge, a series of arches erected during the height of the Roman Empire. Although the bridge currently measures 4.80 meters wide, 30.25 meters long, and 3.17 meters high, it originally stretched wider at 4.8 meters in width and 39.2 meters in length, standing 3.17 meters tall. It was constructed solely from white marble blocks without mortar. The city's Western Walls, standing 4.70 meters tall and extending 118 meters in length, were restored during the Eastern Roman Empire era, utilizing spolia to form the entrance blocks. To safeguard the valuable cultural legacy of the Prusias ad Hypium Ancient City, the Konuralp Museum was founded in 2003. The museum includes three exhibition rooms, a laboratory, two storage areas, a conference hall, and administrative offices. It preserves a collection of 6,237 items, comprising 1,848 archaeological pieces, 491 ethnographic objects, and 3,898 coins.
