During the medieval period Dartford was an important waypoint for pilgrims and travellers "en route" to Canterbury and the Continent, and various religious orders established themselves in the area. In the 12th century the Knights Templar had possession of the manor of Dartford; the National Trust property at Sutton-at-Hone, to the south of the town, is a remaining piece of that history. In the 14th century, a priory was established here, and two groups of friars—the Dominicans and the Franciscans—built hospitals here for the care of the sick. At this time the town became a small but important market town.
