The chapel is located on the upper floor of a two-storey Late Gothic building. It was consecrated in 1482 and features a small bell tower on its façade.
A masonry staircase leads to the Gothic pointed-arch portal. The chapel has Gothic windows, a ribbed net vault and a polygonal choir. Both the interior and exterior walls are decorated with frescoes dating from the 16th century.
Among the exterior frescoes, the most remarkable is a 15th-century depiction of a dead man whose soul is being contested by an angel and a devil. Another fresco, framed by painted marble, portrays the Pietà set in a wide and peaceful landscape from the early 16th century. The lower floor, covered by a barrel vault, originally served as the ossuary.
The artist of the Pietà depicts Christ seated on the Holy Sepulchre together with Mary and John, surrounded by a hilly landscape.
In 1998, numerous human bones, along with devotional objects and medieval coins, were discovered beneath the chapel floor.
