The Ludwigskirche is one of the great Protestant baroque churches of Germany — a light, elegant building in white and ochre designed by Friedrich Joachim Stengel in the 1760s for the court of Nassau-Saarbrücken. It sits on its own square, the Ludwigsplatz, which Stengel designed as a unified baroque ensemble around the church.
The interior is airy and beautifully proportioned, quite different from the dark heaviness of most German churches. The organ is exceptional and the church hosts regular concerts. Free to enter outside services. The surrounding square, with its symmetrical facades and central church, is the most complete example of Stengel's urbanism and worth viewing from a distance as a whole composition.
