This is one of two entrances to the Passage of Birger Jarl, which is the smallest galleria in Stockholm. It was designed by Ludvig Peterson and finished in 1897. You'll see more of it, I promise... If you're wondering who Birger Jarl is, he lived in the 1200s and is commonly held to be the founder of Stockholm.
