Church of the Immaculate Conception, Art Nouveau religious monument in Trnitá, Czech Republic.

The Church of the Immaculate Conception is a religious building in Trnitá, constructed in the early 1900s in the Art Nouveau style. The structure displays flowing lines, curved forms, and decorative details characteristic of this architectural approach.

The church was built in 1910–1913 to designs by Franz Holik, a pupil of Otto Wagner, on the site of a leper hospital with the church of St Stephen, demolished in 1908. Bishop Pavel Huyn initiated it as a jubilee church for the 60th anniversary of Emperor Franz Joseph I's reign; the foundation stone was blessed on 18 August 1910, the emperor's 80th birthday. It was consecrated on 18 January 1914.

The church became the parish church on 20 January 1914, when Bishop Pavel Huyn transferred the parish administration from the Church of St Mary Magdalene. Its main altar was donated by Archduke Friedrich of Austria-Teschen and his wife Elisabeth, whose patron saints stand beside it in bronze.

The building is open for visitors, with access times following the church calendar and service schedules. It is advisable to check local information before a visit to ensure you can enter.

The tower rises 60 metres and is topped by a three-part copper-clad helm. Foundry owner Heinrich Storek donated two steel bells for it. The unstable ground of former marshland required foundations on reinforced-concrete piles.
