The Church of Saint Peter and Paul in Růžová is a baroque-style church located at the heart of this village within the Ústecký region. Constructed between 1710 and 1712 by Christian Lagler, it replaced an older structure and has been under protection since 1966 due to its cultural heritage value. The church holds historical significance not only for its architectural style but also for its connection with notable figures such as František Karel Clary-Aldringen, who held the patronage over the church after its construction.

The origins of the Church of Saint Peter and Paul are rooted in a long-standing religious tradition. The first mention of a parish in Růžová dates back to 1352 when it fell under the deanery of Lípa (now Česká Lípa). By 1562, the parish had become Protestant, reflecting broader religious shifts within Bohemia during that era. However, the current baroque church was built between 1710 and 1712 on the site of a previous structure by Christian Lagler, a builder from Teplice. The patronage over this new construction was taken up by František Karel Clary-Aldringen, a nobleman whose influence is still remembered in connection with the church.

Architecturally, the Church of Saint Peter and Paul exemplifies baroque style, characterized by its grandeur and attention to detail. Christian Lagler's design replaced an earlier building, marking a significant transformation in both form and function for the village's religious center. Although specific materials used are not detailed, the baroque elements would have included ornate decorations typical of the period. The church was originally adorned with artworks attributed to the circle of Petr Brandl, although these pieces now reside in a castle in Děčín.

The history of the church is marked by several key events and figures. In 1712, it was consecrated by Johann Christoph Müller, an event attended by the noble family of Clary-Aldringen. The church's significance continued through various administrative changes; for instance, after a period under the vicariate of Česká Kamenice, it came under Děčín's jurisdiction in 1912. Mons. Robert Franze served as its pastor until 1946. Post-World War II, the church faced neglect during the communist regime, leading to deterioration and eventual devastation by a fire on August 1, 1988. This fire was caused when Benno Rössler, then spiritual administrator, carelessly burned dry grass near the church, resulting in extensive damage.

Despite these challenges, the Church of Saint Peter and Paul underwent a complete reconstruction from 1996 to 2000, thanks to the efforts of pastoral assistant Mgr. Marcel Hrubý and his team. The restoration preserved its historical essence while incorporating new furnishings sourced from other churches: altars from Dubnice v Podještědí, organs, baptismal fonts, and statues of Saint Peter and Paul from Zahořany u Litoměřic, and sculptures from Markvartice. Statues of apostles now stand on the entrance ramp, adding to its historical ambiance.

Today, the Church of Saint Peter and Paul stands as a testament to resilience and cultural heritage in Růžová. It is accessible for visitors who wish to explore its rich history and architectural beauty. The church's significance extends beyond its religious function; it serves as a cultural landmark that reflects the broader historical narratives of Bohemia, particularly during the baroque period under the Habsburg Monarchy. Its story of destruction and rebirth adds an intriguing layer to its allure.

Visiting this monument offers a unique opportunity to connect with the past while appreciating the efforts made to preserve such heritage for future generations. Whether you are drawn by architectural interest or historical curiosity, the Church of Saint Peter and Paul in Růžová is a compelling destination that invites exploration and reflection on its enduring legacy.
