The first timber – earth castle in Penmark was probably erected by the de Umfraville family in the early 12th century. It was done by their first known representative, Gilbert de Umfraville, or his successor, Robert. Two centuries later, the castle was transformed into a stone building. The first reference to it is from 1307. It was inhabited by the Umfraville family until the twenties of the 14th century, when, through the marriage of Elizabeth Umfraville, it became the property of Oliver de St John. In subsequent centuries, the castle was leased to various people and gradually declined. Finally, the ruin turned into a ruin in the seventeenth century, serving as a source of free building materials for nearby farms.
The fortified wall of the castle, about 1 meter thick, marked a inner ward measuring 65 by 47 meters. On the north-west side was a tower with a diameter of 7 meters with a rectangular latrine turret or annex to the south. The outer defense zone was the moat.
The castle is in a state of ruin. There are visible fragments of the defensive wall and the ruin of two floors of the tower with a latrine annex. In addition, on the western side there is a later, narrower sixteenth-century wall. The western wall also includes the ruins of the barn, which from the outside resembles the rest of the ruins, but is in fact a much later building, erected in the eighteenth century, using material from non-existing parts of the walls. Entrance to the castle is free.
