The chapel dates from the mid-fourteenth century. It is presumed that it was originally a chapel at the margrave estate or merchant guild or a hospital chapel. In the 16th century, there was a sheepfold and a brewery, in the 18th century a salt warehouse, and in the nineteenth century a fire brigade. Currently, chapel is the seat of the Museum of the Lake District in Myślibórz.
Holy Spirit Chapel was built in the south-western part of the town, within the defensive walls. It received a form on a rectangular plan, made of granite blocks in the lower parts, and bricks in the upper parts. Its facades were decorated with round blendes and a decorative brick frieze under the cornice. It is covered from the outside with a gable roof, while the interior has a wooden beam ceiling.
