The monastic complex in Rywałd Królewski consists of a baroque church of St. Sebastian and a monastery with outbuildings and a garden. The current church was built between 1710-1738 at the initiative of the Czapski family and was handed over to the Capuchin fathers who arrived from Warsaw in 1748. The interior design is late Baroque and includes: the main altar from the mid-18th century with a Gothic sculpture of the Mother of God Enthroned with the Child (the so-called Gypsy Mother of God) from the end of the 14th century, six Baroque-classical side altars from the turn of the 18th/19th centuries, a pulpit, confessionals, and an 18th-century baptismal font. The dominant color of the furnishings is bronze, which is the color of the habits of the Capuchin friars.
