Originally built in 1847-1850, it was the first church constructed in Ełk after the Great Fire of 1824.
The building functioned as a Lutheran church for nearly a century before being transferred to the Catholic Church in 1945.
Its architectural design is representative of the Rundbogenstil (round-arch style) popular in mid-19th-century German religious buildings.
The church narrowly avoided destruction during the heavy fighting in Ełk during the final stages of World War II.
It is one of the few surviving historical buildings in central Ełk that retains its pre-war exterior appearance.
The Church of the Most Sacred Heart of Jesus in Ełk is a historic neo-Gothic structure originally constructed as a Protestant church in the mid-19th century. Following the Second World War, the building was repurposed for Catholic worship to serve the local community. It features a distinctive red-brick facade characteristic of the region's 19th-century ecclesiastical architecture. The interior has undergone several renovations to accommodate Catholic liturgical needs while retaining its historical core. It serves as an active parish church under the Ełk Diocese, maintaining regular community and religious activities.
