House at the White Unicorn (U Bílého jednorožce)
In the cellar of the house, remnants of the original Romanesque building with Gothic vaults can still be found. In the 19th century, the house hosted the Pharmacy at the White Unicorn, named after the house sign from the 16th century – a lamb with a horn.
In the early 20th century, the property belonged to the couple Berta and Max Fanta. Max Fanta, a pharmacist, invented the Fantashell here. Berta Fanta ran a literary salon on the first floor, which served as a meeting point for well-known Prague intellectuals, including Franz Kafka, Samuel Hugo Bergmann, Franz Werfel and Max Brod. The founder of anthroposophy, Rudolf Steiner, and the renowned physicist Albert Einstein, who taught at Prague University from 1911 to 1912, were also guests. A bust of Einstein next to the entrance commemorates his visit today.
