The construction of the Speyer Memorial Church at the end of the 19th century was an expression of the cultural struggle between Catholics and Protestants. The elaborate construction of the building, which was to resemble Speyer Cathedral with its white-grey Vosges sandstone, was also highly controversial among Protestant Christians. In the vestibule of the neo-Gothic-style church, the Luther monument and statues of Protestant princes commemorate the protest of the Protestant imperial estates at the Diet of Riches in Speyer in 1529. Today, the Speyer Memorial Church has the tallest church tower in the Palatinate. With a total of 95 stops, the organ is the largest in south-west Germany and the second largest mechanical organ in the world.
