Billy Idol - Sweet Sixteen
I’ve always wondered who the man is in the opening frames of Sweet Sixteen, captured among geometric blocks of stone.
My curiosity led me to investigate, uncovering a tear-jerking story.

The site is called Coral Castle and it is an architectural structure made of limestone designed in Homestead, Florida, by Edward Leedskalnin (the man in the frame), a Latvian-American amateur sculptor. The structure consists of large stone blocks shaped and carved into walls, large tables and chairs, bas-reliefs, and a habitable tower. Since 1984, it has been a monument included in the U.S. National Register of Historic Places.

According to Joe Bullard's biography, at the age of 26, Leedskalnin was left by his 16-year-old fiancée Agnes Scuff the day before their wedding. Out of disappointment, the young Latvian supposedly conceived the idea of building a castle to impress his beloved, a goal later achieved with the construction of Coral Castle, but which didn’t yield the desired success with the woman.

Sweet Sixteen, the video of which was filmed at Coral Castle, is directly inspired by the relationship between the sculptor and Agnes Scuff, whom he called Sweet Sixteen, which was the basis for the creation of the work.
