Stockholm's narrowest street (Mårten Trotzigs gränd)

"Mårten Trotzig's alley is an alley in Old Town, Stockholm, and was named in 1949. The alley is only 90 cm wide and is thus Stockholm's narrowest alley. The name is after the German merchant and burgher, Mårten Trotzig, who immigrated to Sweden in 1581 and bought properties at the alley in the Trivia quarter in 1597, 1599 and 1600. This narrow alley may have been called Trångsund during the Middle Ages, in 1544 it is referred to as den tronge trappe grenden, and in 1608 it is called Trappegrenden and, according to a stone tablet on the facade, also Trånga Trappgränden. It is uncertain when Mårten Trotzig's name was first associated with the alley, but it must have happened no later than 1733; it is called Trotz alley on Petrus Tillaeus' map. In the middle of the 19th century, the alley was closed by planks at both ends, but it was reopened in 1945. Mårten Trotzig's alley has 36 steps leading from Prästgatan down to Västerlånggatan at Järntorget. The alley has given its name to Restaurant Mårten Trotzig, which is located on Västerlånggatan where Mårten Trotzig's alley opens out."
