Sacred Heart Church, Székesfehérvár, Catholic church in Székesfehérvár, Hungary.

The Sacred Heart Church is a central-plan building on a Greek cross, with two side niches and twin bell towers flanking the entrance. Its octagonal reinforced-concrete dome, topped by a metal-clad lantern with windows, rises above the towers. A mosaic of Christ sits over the main door, and Jenő Bory's Madonna sculpture stands inside.

The building was constructed in 1911 under architect Jenő Bory's direction as Hungary's first reinforced concrete religious structure. It evolved from a former chapel of an institute and orphanage into an independent parish church.

The parish was established in 1928, with Lajos Kocsis as its first priest, and the church became its parish church. Its feast day, the kermesse, is held on the feast of the Sacred Heart. The bells in the two towers were cast by Ferenc Walser in Pest and are older than the building, probably kept from the earlier chapel.

The building sits on a central street, making it straightforward to find and reach on foot. Visitors should note that access may vary depending on religious services and ceremonies taking place.

The building was technologically groundbreaking in 1911, being the first religious structure in Hungary to use reinforced concrete. This material choice allowed the unusually geometric forms that characterize it today.
