Martinskirche Isingen, Late Gothic church in Isingen, Germany.

Martinskirche Isingen is a plastered hall church with a steep tiled saddle roof, a long nave and a higher polygonal choir braced by grey stone buttresses between tall pointed windows. The square choir-flank tower, medieval in its core, rises at the rear right under its own steep roof. Inside, a net-rib vault with faint floral painting spans the space, and a wooden organ with light-coloured pipes stands above the altar.

A Romanesque stone church is documented at Isingen in 1140, and remains of it are still visible. The nave and choir were rebuilt in the 15th century and completed in 1451; the tower core dates from the 13th century. Since then the church has seen no major structural changes.

The church bears the name of Saint Martin of Tours, and its late Gothic pulpit retains a Baroque basket added later. On the gallery railing hangs a 1636 epitaph depicting the beheading of John the Baptist, a panel visitors can pick out from the pews. The organ, built by Gebr. Link in 1885, reuses older pipes and was renovated in 1948/49.

The church stands in a walled churchyard in Isingen, a district of Rosenfeld. The parish is part of the Verbundkirchengemeinde Rosenfeld-Isingen in the Kirchenbezirk Balingen. As an active parish church, it is best to check service times or contact the parish office before planning a visit inside.

The source records that three medieval bells hang in the tower of the Georgskirche, not the Martinskirche, and gives no casting dates. What the Martinskirche does hold is a 1516 baptismal font and a 15th-century crucifix, both late Gothic. The organ by Gebr. Link was installed in 1885 with older pipes and renovated in 1948/49.
