Legend connects temple erection with epidemic, which decimated the population of Sokolow. One of them, coming back at night from common prayers of plague cessation, saw a mysterious character. It was St. Roch, who promised the population of Sokolow to rescue them if they would erect temple on nearby meadows. At the time, when new temple was being erected, epidemic expired. In memory of this event church was named after St. Roch, patron of people sick with plaque.
The inventory of 171 of Sokolow church mentioned about a small church placed behind parish facilities: the church of St. Roch, at the roadside, constructed on the same land, needed significant repairs, foundations, floor, roof and fencing. In 1797, the city suffered fire. Probably, old wooden church of St. Roch was damaged. It was rebuilt from funds of the foundation of Karol and Franciszka Kobylinski in 1819 or in 1820, to serve in the years 1820-1826 as temporary chapel for just uplifting masonry parish temple (in 1817 wooden church of St. Michel Archangel Michael of 1800 burned down).
