The side altar of St. Anthony of Padua in the Reformed Church in Kęty was made in 1711-1715 by Brother Modest Gronalewicz. Together with the high altar and two side altars, it is one of the oldest furnishings in the temple. The form of the reredos constitutes an example of a solution typical to the furnishings of Reformati temples. A particularly close analogy are the side altar structures at the Reformati church in Jarosław.
