The Gedächtniskirche der Protestation ('The Memorial Church of the Protestation') was built between 1893 and 1904. It was constructed in memory of the protest that took place at the Diet of Speyer by the Protestant states of the Holy Roman Empire in 1529. The tower is the tallest bell tower in the palatinate with 100 m. Its construction was supposed to be a reminder of the protest action that the imperial evangelical states brought to bear in 1529 at the Reichstag in Speyer. The Luther memorial in the vestibule and the adjacent statues of local Protestant rulers serve as reminders of this event.
During the cultural struggles at the end of the 19th century, relationships between Catholics and Protestants were tense. That had its impact on the construction of the Memorial Church which was, under no circumstances, to be any less assertive than the Cathedral. In any event, the construction was controversial, even for evangelical Christians.
The Protestants collected donations and even gained the support of Kaiser Wilhelm II and his wife, who donated the glass window in the apse. Following the plans of Julius Flügge und Carl Nordmann, the church was built very lavishly out of white-gray Vosges sandstone.
In 1979, the organ was replaced. The current organ comes from the Detlef Kleuker workshop and is, with its 95 registers, the largest organ in southwest Germany and the second largest mechanical organ in the world.
Organ concerts and matinees take place regularly in the Memorial Church.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
