In the late 19th century, a windmill was erected on an old grave mound. It had already been built in 1775 on the neighbouring island of Sylt but was later relocated to Süddorf. Today it is used as a dwelling house. On the southwestern edge of Süddorf, there is the "Satteldüne" sanitorium, which specialises in the treatment of diseases of the respiratory system of children and adolescents. Moreover, Amrum's school house, the "Öömrang Skuul" with elementary and secondary divisions, is located in this part of Nebel. South of Süddorf, still within the municipality's limits, the Amrum lighthouse is located. It took up service on January 1, 1875 and it has got the second-highest navigational light along the German North Sea shores next to the light of Heligoland. The tower is built on a 27 m high dune. The fire itself is located at 63 m above sea level and carries as far as . The lighthouse is Amrum's most prominent building. Since the municipal elections of 2008, the "Nebeler Bürgerblock" holds seven seats, the CDU holds three and the SPD holds one seat of Nebel's municipality council. Another mill, built in 1771 by Erk Knudten, hosts a museum of local history which also features exhibitions of works by various artists during the summer months. It is a Dutch horizontal type mill which was in use until 1962. Pastor Erich Pörksen saved the building from being torn down by founding a society for the preservation of the Amrum windmill in 1963. The mill is still operable today. Opposite of the windmill, the Graveyard of the Homeless is located, where unidentified drowned persons are buried. Most graves date back to the early 20th century, the youngest being from 1969. Since then, all bodies washed ashore on Amrum's beaches could reliably be identified due to improved forensic techniques. Each tomb is decorated with a simple wooden cross into which the date of the body's retrieval from the sea is encarved. The navigational light "Nebel", erected in 1981, is a modern aluminium construction of 9.6 m height. Due to its location, this leading light for the "Norderaue" channel has a height of 16 m above mean high tide sea level and carries as far as . The "Öömrang Hüs" at Waaswai 1, Nebel, is a largely original ancient Frisian house from around 1751 which is owned by the folklore society "Öömrang Ferian".
