Ludwigskirche and the surrounding Ludwigsplatz (Ludwig's Square) were designed as a "complete work of art", in the sense of a baroque place royale, by Friedrich Joachim Stengel on the commission of Prince William Henry.

The main reason for this long delay was the fierce dispute, which lasted from the 1950s into the 1970s, about whether the baroque interior, which had been completely lost, should also be reconstructed according to the original plans.

After the reconstruction of the "Fürstenstuhl" (i.e., the princely seating in the gallery across from the organ) in 2009, the interior is more or less complete, but more than half of the balustrade figures on the outside are still lacking as well as the exterior finish (c.f.

The arrangement with the altar, pulpit and organ was rather usual for a Lutheran church built in the 1700s, and it had already been used by Stengel in some of his earlier buildings.

The other axis points over the exit, which faces the Saarland state chancellery today, toward the former royal summer residences on Ludwigsberg, the so-called Ludwigspark.

Whether it was already lost during the 19th century or during the air raid 1945 is not clear, but it would be important for fitting the church into the surrounding buildings of the square.

Even during construction, this concept was changed, so that the building on the east (in which the Ludwigsgymnasium was housed) was split in two, in favor of a view toward St. Johann (the "Stengel axis", today marked by Wilhelm-Heinrich-Straße).

In contrast to that is the place that Stengel intentionally left open for the view toward Ludwigsberg, which is today occupied by the state chancellery.

As the symbol of the Saarland state capital of Saarbrücken, Ludwigskirche is shown on the German 2 euro commemorative coin in 2009.
