Siófok, which was called "Fok" in the medieval era, has written records dating back to 1488 regarding its first church. The medieval church was destroyed during the Turkish occupation, and in its place, returning settlers built a small wooden church in 1693. Later, in 1736, a new Baroque-style church was consecrated in honor of the Immaculate Conception of the Virgin Mary.
By the end of the 19th century, Siófok had become a popular resort destination, and the population continued to grow. The more than 150-year-old Baroque church was in poor condition and proved to be too small for the increasing number of inhabitants. In the early 1900s, a decision was made to construct a new, larger church. The old church, except for the tower, was completely demolished, and the new church was built based on the plans of the architect Károly Csomay from Veszprém. The neo-Romanesque-style church was consecrated on July 3, 1904, in honor of the veneration of the Virgin Mary under the title "Sarlós Boldogasszony" by Bishop Károly Hornig of Veszprém.
Above the main entrance of the church, there is a painting by Endre Muzsinszki Nagy, and the triumphal arch features frescoes by György Leszkovszky, an academic professor. Inside the nave, visitors can see station paintings by Béla Büky and sculptures by Lajos Krasznay.
The stained glass windows on the facade were made in the workshop of Miksa Róth in Budapest.
The church houses the largest organ in the Balaton region with three manuals, 36 registers, and 2432 pipes, built by the organ builder Frigyes Paulus.
