The first timber watchtower, protected by lakes and swamps, was built by the Teutonic Order around 1280. Initially, the Mohrungen Castle served as a teutonic pfleger’s office, and then, from 1331, a vogt’s seat in the Elbląg commandry. Work on its construction was completed around 1380.
During the Polish-Teutonic war in 1414 the castle was conquered by Polish armies. Again, the castle was captured by units of the Prussian Confederation during the Thirteen Years’ War. At the end of the war, the castle was recaptured by an oberstspittler and Elbląg commander, Henry Reuss von Plauen, one of the prominent Teutonic leaders. As a result of the Second Peace of Toruń from 1466, the Order lost, among other things, Elbląg, and thanks to Plauen, the new seat of the commandry was placed in Morąg. However, it survived only until 1474, then the pfleger’s office was restored.
After the construction of a palace in the western corner of the city walls at the end of the 16th century, the process of degradation of the castle began, although in 1584 the builder Blasius Berwart carried out its renovation on behalf of margrave Jerzy Fryderyk. In 1616, the main castle tower collapsed, and during the Swedish wars the buildings suffered further damages. In the nineteenth century, the castle was largely demolished.
The castle was built on a wide promontory entering the Morąg lake. From the south and west it was near the waters of the lake, and from the east and north it was protected by the moat, fed by the waters of the Mill stream. On the north-east side, the town was located, but it was a separate defense system, not connected with the castle.
The stronghold was a three-range complex on a plan similar to a trapezoid with dimensions of 55×75 meters. The entrance gate was located on the north-west side. It was flanked by the main tower on a round base. From the lake side, in the south – east corner, a main castle house with cellar was erected. In its relics, two ground floor rooms were discovered, which were probably topped with rib vaults. Unfortunately, the exact functions of individual castle ranges and the layout of its rooms are not known. In the neighborhood of the house, in the south corner, there was a small four-sided tower, and in the eastern corner, a higher, cylindrical tower was later added. The whole was surrounded by the second circumference of the walls, which created the area of zwinger. By it, around the entire castle, led the entrance to the inner courtyard. After raising the rank of the castle to the vogt’s seat, the castle courtyard was enlarged, and two side ranges were added to the main house. Its plan then obtained a shape similar to the letter “U”. Probably from the west it adjoined the economic outer ward of the castle.
Two heavily rebuilt and lowered castle wings have survived to this day. North-west with the gate and much later north-east wing separated from the city by a moat. Since 2001, the castle area belongs to a private owner, who unclossed and secured some of the surviving walls. In 2002, renaissance polychromes of rich ornamentation, floral elements and interesting images of male and female figures were discovered on timber ceilings of the gatehouse building.
