The Fort of Parkan (full name Ciğerdelen Parkan meaning "liver-stabbing fort", also called Çekerden) was a fortified outpost built by the Ottoman Empire in 1546 as part of the defense system of Esztergom. It lost its military role after 1686 and was soon demolished. The fort was located on the territory of present-day Štúrovo, Slovakia.
The crossing of the Danube near the mouth of the river Hron already had a strategic role in Roman times when probably a small fort was built in this area. Later there was an important medieval village first mentioned in written rekord in 1075 as Kokot.[1] This settlement was totally destroyed in 1543 during an Ottoman invasion.[2]
The Ottomans built a small fortress (parkan) west of the site of the destroyed village as part of the defense system of Esztergom in 1546.[3]
