In Spiazzi, at 700 m above sea level and halfway up the vertical rock face of Monte Baldo, the Sanctuary is carved out of the bare rock, standing over a 400 m sheer drop. The left hand walls and the apse are actually made from the rock itself. The sanctuary is dedicated to the 'Madonna Addolorata' but is called the 'Santuario della Corona' (sanctuary of the crown) due to the shape of the surrounding rocks. The original building around which the rest of the sanctuary was later built dates back to the XVI Century and was constructed to house a stone statue representing the Pietà, which is still worshipped today. In 1625 the church was extended and became the central nave of a larger structure.

The paths and stairway leading to the sanctuary were also added. Further extension work was carried out in 1899, when the bell tower and façade were redone and from 1975 to 1978. According to legend, a stone statue of the Pietà disappeared from Rhodes upon the arrival of the Turks in 1522 and reappeared miraculously one night at Spiazzi. The mountain folk, struck by the brilliant light and sound of music accompanying the apparition, went to the site and used ropes to carry the statue to the top of a cliff, setting it in a wooden chapel. The following night, however, the statue returned miraculously to the site where it had appeared the first time. Out of respect for the evident wishes of the Madonna, the people started to build a chapel on the rock face. In reality, it would appear, from the inscription on its base, that the statue was commissioned by the local lord Lodovico Castelbarco, to give it to a group of hermits living near to where the sanctuary stands today.
