Sommerau Castle was built on a rock spur around which the Ruwer river flowed on three sides. In the 13th century the castle was built by the Trier knight family 'von der Brücke', who had their ancestral seat in the Barbarathermen. The castle had fallen into disrepair by the beginning of the 19th century at the latest.
The facility measures 40 x 10 m. In the west, the remains of the former palace or residential building tower up to a height of 10 m, and in the east, the four-storey square keep, which with its four floors also served as a residential tower, is around 16 m high. Apparently an ascending wooden battlement led to a door about 3 m high. To the south on the fourth floor there is a large rectangular door with a toilet bay, the masonry of which is placed on consoles made of red sandstone. The residential building shows, recognizable from the inside, three full floors and half a fourth with the protruding remainder of a chimney that begins on the second floor. Only remnants of the rising masonry can be seen of the surrounding wall that supported the battlements. The remaining transverse walls are in the ground, the ground plan can only be determined through excavations.
Today the ruins are freely accessible.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
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.
