Steinfurt is a city in North Rhine-Westphalia, Germany. It is the capital of the district of Steinfurt. From c. 1100–1806, it was the capital of the County of Steinfurt.

A moat is a deep, broad ditch, either dry or filled with water, that is dug and surrounds a castle, fortification, building, or town, historically to provide it with a preliminary line of defence. In some places moats evolved into more extensive water defences, including natural or artificial lakes, dams and sluices. In older fortifications, such as hillforts, they are usually referred to simply as ditches, although the function is similar. In later periods, moats or water defences may be largely ornamental. They could also act as a sewer.
