St. Antonius (Tönisberg)

A chapel called "Sanct Antonius am Berghe" already stood at Ryckendael in the early 14th century, giving the village its later name. It held altars dedicated to St. Anthony and St. Cornelius, and in 1439 Duke Arnold of Guelders donated sixty morgens of land for the upkeep of a priest. The chapel served as a mortuary in the 19th century until it burned down in 1888. After the parish was founded, construction of a 30-metre-long, 7-metre-wide church began in 1537; it later received a Baroque high altar of the Ascension in 1662, plus two side altars for St. Anne and the Immaculate Mother of God. Grave slabs of clergy and the crypts of local noble families, who also had their own pews, once lay within the church.

Following the liturgical reform of the Second Vatican Council, Pastor Wiegels redesigned the interior: Karl Franke created the bronze altar facing the congregation, depicting scenes from the Easter story, along with an ambo and tabernacle. The high altar's retable was moved to the choir's rear wall; the high altar itself was restored by 2005 and is framed by choir stalls, while the old pulpit was removed. The 1919 murals by Tönisberg church painter Karl Heil were largely uncovered again during restoration between 1982 and 1991. The three figurative choir windows of 1898/99, depicting the life of St. Anthony, were designed by Friedrich Stummel and executed by the Wilhelm Derix glass-painting workshop; the two side choir windows from the Peter van Treek workshop are abstract in red and blue. The baptismal font of pink marble was a gift from the Bishop of Roermond for the church's first consecration, and its bronze lid from 1968 depicts an ark amid waves, surrounded by animal and plant life.

The organ, built in 1927 by the Fabritius and Brehm workshop in Kaiserswerth, has 17 stops. Its console features two manuals, pedal, and a swell box; the organ operates purely pneumatically, powered by a wind motor.
