Strada sforii (Romanian for 'String street', Fadengasse ) is the narrowest street in the city of Brasov. It is believed to be one of the narrowest streets in Europe (Spreuerhofstraße, in Germany, and Parliament Street, in England, are narrower).
It is situated near Schei Gate and it is perpendicular to Strada Cerbului (Stag Street). It was initially built as a corridor that firemen could use, and it is first mentioned in 17th century documents. Strada Sforii is now a tourist attraction and meeting spot. Its width varies between 111 and 135 centimeters, and it is 80 meters long.
