The Selke valley is the site of the former BenedictineHagenenrod Abbey, a filial monastery of Nienburg Abbey founded in 975. The Nienburg monks obtained market, minting and customs rights by King Otto III in 993. About 1000, the local Schwabengau counts of Ballenstedt, progenitors of the noble House of Ascania, served as Vogt protectors. Though the estates were placed under protection by Pope Alexander III in 1179, the monks later resettled to Naumburg and the premises, devastated during the German Peasants' War in 1525, decayed.
When the Ascanian Princes of Anhalt had the region developed as a mining area, a gallery was excavated for pyrite in 1692. Mining was resumed under Prince Frederick Albert of Anhalt-Bernburg from 1759 onwards, and sulfur was produced by destillation. The healing properties of the waters were first examined in 1766, however, initial attempts to establish a medical care and spa business were not successful.
Alexisbad soon became a fashionable health resort. Among the first guests was the composer Carl Maria von Weber in 1820. On 12 May 1856, the Verein Deutscher Ingenieure (Association of German Engineers, VDI) was founded here during a vacation of several academics.
Tourism
The economy of the village is dominated by tourism. There are several hotels, pensions and restaurants. Hiking trails lead into the attractive local countryside. Typical destinations are:
The Betrothal Urn (Verlobungsurne) - a monument at a good viewing point above the town (checkpoint 177 in the Harzer Wandernadel hiking system).
The Köthen Hut (Köthener Hütte), checkpoint 195 in the Harzer Wandernadel hiking system. The hut may be reached on a steep zigzag path that runs from the B 185 road below where there is a small, unsigned, parking bay. Otherwise walkers need to start from Alexisbad, Harzgerode or Mägdesprung.
Notable people
The author Walter Kempowski (1929–2007) spent his summer holidays in Alexisbad in 1939. He perpetuated the resort as Sophienbad in his 1971 autobiographic novel Tadellöser & Wolff.
