> Empress Elisabeth of Austria, famously known as Sisi, spent her early years as a Bavarian princess in Munich before becoming one of the most fascinating figures in European history. She is often referred to as “Sissi“ due to the beloved film series starring Romy Schneider, which brought her story to international audiences. …

> Hard to believe, but Empress Elisabeth was actually tattooed. Due to her love of the sea, she had a blue anchor tattooed on her left shoulder blade in a harbour pub at the age of 51.

> Mysterious, rebellious, stylish and incredibly modern, the real Elisabeth of Austria was different from how she has been portrayed for years in various films and plays inspired by her life. Few people know that the Empress also had a tattoo, further proof of her unconventional temperament, since getting tattooed was not very common at the time, especially for an aristocrat. Being very fond of the sea, in 1888 Sissi had a small black anchor tattooed, perhaps during one of her many trips. At the Wachsfigurenkabinett, the wax museum in Vienna, her statue appears as in the famous painting that Franz Xaver Winterhalter made for her, in a white formal dress, with the diamond stars pointed in her hair and bare shoulders. And on the left shoulder is the famous tattoo.
