Camillus de Lellis church in Tarnowskie Góry, Roman Catholic filial church in Osada Jana, Tarnowskie Góry, Poland

Camillus de Lellis church is a brick building in Tarnowskie Góry designed with traditional Silesian architecture, featuring red walls and pointed arches throughout. The exterior displays symmetrical proportions and characteristic details typical of early 20th-century design.

The cornerstone of the complex was laid on 3 June 1906; the design was by Emanuel Dziuba of Tarnowskie Góry and the work was coordinated by Father Christian Adams of the Camillians. The hospital, church and monastery were consecrated on 11 June 1907 after 370 days of construction. A separate parish was erected here on 1 January 1942, and since 16 October 2004 the building has served as a filial church.

The church is dedicated to John the Baptist and Camillus de Lellis, the patron of the sick and of the Camillian order. The Camillians ran a hospital for alcoholics here from 1907, and the church served as a garrison church for German soldiers during World War II. Since 2004 it has been a filial church of the Parish of Our Lady Healer of the Sick.

The church opens for prayer from morning until evening on weekdays and welcomes visitors during regular services on Sundays and holy days. Plan your visit around these service times and observe standard conduct expected in a place of worship.

The organ, built in 1930 by Gebrüder Rieger of Krnov, stands on the gallery above the main entrance and has a neo-Gothic case, pneumatic action, two manuals and a pedal. The church was consecrated on 11 June 1907 as part of a Camillian hospital and monastery complex.
