St. Francis Church is situated next to the Franciscan monastery. In front of it there is a small square, formerly used as a cemetery. The construction of the church and the monastery reaches back to the year 1301. Despite many restorations, traces of the period in which the church was built can still be seen in the presbytery.

The present interior dates from the 17th century and the exterior from the 19th century. The left corner of the church is decorated in the Lombard style. The baldachin in front of the central altar dates from the 16th century. It was removed in the 18th century and restored to its original dwelling in the 19th century.

Next to St. Francis Church is a Franciscan monastery with a gracefully designed atrium, the Cloister, which represents one of the best Cloister atrium designs in the coastal area. Leading to the Cloister there is a half-arched portal adorned with richly carved columns, bearing an architrave with an inscription and coats of arms.

In its entirety as well as its detail, the portal is considered to be the best example of stone carving art from the end of the 17th century in Piran. Due to its beautiful atmosphere and good acoustics, the Cloister has for many decades been the setting for the Musical Evenings of Piran.
