Evangelical Church, Religious landmark in Saarlouis, Germany

The Evangelical Church in Saarlouis is a hall church with a Greek-cross plan and a prominent corner tower topped by a neo-baroque curved roof. Its facades mix neo-gothic and neo-renaissance elements, built on a black basalt base with yellow sandstone walls and red-framed doors and windows. Inside, a light ribbed vault covers the central space, with galleries in the four cross arms.

Saarlouis, founded in 1680 as a French fortress town, only allowed a Protestant congregation after the fortress passed to Prussia in 1815. King Frederick William III had the former fencing hall, the "Salle des Cadets", converted into a garrison church. After the fortress status ended in 1889 and the garrison chaplaincy was dissolved in 1893, the congregation built a new church on the razed Bastion V; the foundation stone was laid on 22 August 1904 and the church was inaugurated on 29 June 1906.

The church's interior follows the Wiesbadener Programm: altar, pulpit and organ are stacked vertically. The pulpit, an octagonal basket set into the wall, carries copper relief panels of the Sower, the Good Shepherd, the Good Samaritan and the Prodigal Son. A menorah stands in the chancel, referring to the Jewish roots of the Christian faith.

The church stands at Kaiser-Wilhelm-Straße 2, with the parish house from 1902 next door at Kaiser-Friedrich-Ring 46. The main portal faces the street beneath the corner tower; the interior is entered from there. Two oaks grown from acorns of the Wittenberg Luther oak stand in front, planted in 1910.

The yellow sandstone came largely from the demolished fortress of Saarlouis, and the blocks themselves were quarried at Limberg near Wallerfangen. Two oaks grown from acorns of the Luther Oak at Wittenberg were planted in front of the church in 1910; another oak behind it comes from the Sachsenwald.
