Saint James the Grater church in Oelsnitz/Vogtl., Religious monument in Oelsnitz, Germany

St. Jakobi in Oelsnitz is a late Gothic hall church with an asymmetrical plan, a transept and a polygonal choir. Its two towers, square below and octagonal above with spires, rise 73.5 m. The plastered rubble-stone walls have buttresses and steep slate roofs; inside, a star vault on slender octagonal piers spans the two-aisled hall, with galleries wrapping the nave and choir.

St. Jakobi was first documented in 1227; the tower bases date from the 13th century and the foundations and crypt from 1340. The present structure results from a rebuild between 1488 and 1588, with further work after fires in 1634 and 1720. After the town fire of 1859 the church was remodelled in Neo-Gothic style, and the 73.5-metre tower tops were added in 1867/68.

The church's name refers to the apostle James, and the parish belongs to the Evangelical-Lutheran Church of Saxony. Its 1930 Jehmlich organ, with 65 stops on three manuals and pedal, is the largest in the Vogtland; it reuses pipes from Christian Gottlob Steinmüller's 1841/42 instrument and was restored in 2005 by Thomas Jann. The four-bell ring mixes two cast-iron and two bronze bells in an oak bell frame.

The building can normally be visited, with regular worship services and occasional concerts taking place that determine its use. It helps to check local opening times, as access can vary depending on events and time of day.

The largest organ in the Vogtland is housed here: built by Jehmlich in 1930, it has 65 stops on three manuals and pedal, reusing pipes from Christian Gottlob Steinmüller's 1841/42 instrument. It was restored by Thomas Jann in 2005 and given a new setter combination. The ring consists of four bells, two of cast iron and two of bronze.
